Re: [U-Boot] Run hello world with Uboot !

2008-10-08 Thread thaoth 

Hi All,

Following guide at http://www.denx.de/wiki/DULG/UBootStandalone

1. Load hello_world.srec into SDRAM

= loads
## Ready for S-Record download ...

## First Load Addr = 0x8E00
## Last  Load Addr = 0x8E000157
## Total Size  = 0x0158 = 344 Bytes
## Start Addr  = 0x8E00

2. And Run

= go 8e00
## Starting application at 0x8E00 ...


U-Boot 1.3.4-00404-gab00e7a-dirty (Oct  8 2008 - 11:47:35)


3. hello_world crash and UBoot reset.

4. Here is information of hello_world

#nm examples/hello_world

5. Physical start address of SDRAM is 8c00 and 

#define CONFIG_LOADADDR 0x8e00

6. I didn't have JTAG interface so I couldn't debug it. 

Could I have a help? Anyone had same issue please tell me your idea? Thank
you alot.

This same the porting of UBoot on TEngine/SH7727 has the issue. But we don't
know what trouble shooting steps.

Hi,

2008-10-03 Thread thaoth 

Hi Michael,

Have you try to load your image using tftpboot and put it in memory?
My board don't have Eth port, so we can't try tftpboot 
Are you sure that you don't have any problem with memory initialization?
i think i don't have any problem with memory initialization, because i can
see my image(using iminfo) on memory.

Best regards,

Re: [U-Boot] [UBoot] Hows to boot Linux Kernel from USB

2008-10-01 Thread thaoth 

I think I made a mistake; I didn’t describe my problem clearly. So, now I fix
it.
My purpose is: find out a way to boot a Linux Kernel from USB (FAT16). 

Here are the steps I‘ve made:

 1. Get some kernel images (zImage, uImage) which I built (kernel version
2.6.22.11).
 2. Go to the board (T-Engine/SH7727) which is ported U-boot and try some
commands:
 a. usb start
 b. fatload usb 0:1 0x0020 uimage
 c. bootm 0x0020

And I always get this error:
Wrong Image Format for bootm command
ERROR: can't get kernel image!

I didn’t set ‘bootargs’ and root file system because I think they will have
no effect 
NOTE: 
CFG_SDRAM_BASE = 0x8c00
CFG_LOAD_ADDR = 0x8e00
Some results, I checked: 
 [EMAIL PROTECTED] boot]# file uImage 
 uImage: PPCBoot image

I also tried: mkimage -A sh -O linux -T kernel -C gzip -a 0x8e00 -e
0x8e00 -n Linux  -d linux.bin.gz uImage

best regards

[U-Boot] [UBoot] Hows to boot Linux Kernel from USB

2008-09-30 Thread thaoth 

Hi All,

I would like to know how to boot linux kernel from USB. I have ported UBoot
(support serial, USB driver) but didn't support CF card. 

Would you please tell me how to boot Linux Kernel from USB Flash memory? I
have many guide could help hows to boot Linux kernel from CF card or network
but  I didn't see help for USB Flash memory.

Here is step by step I did but didn't work.
- First initialization USB

= usb start

- List file on USB Flash memory

= fatls usb 0:1
  3876248   vmlinux.srec
  1348231   vmlinux
  2207942   vmlinux.bin
.
  1277956   zimage

- load zImage into SDRAM memory at base address 0x8c00 + 20 

= fatload usb 0:1 20 zimage
reading zimage
.
.
.
.



1277956 bytes read

= bootm
Wrong Image Format for bootm command
ERROR: can't get kernel image!

This seems here is wrong command. I should load uImage (not zImage) into
SDRAM memory. Google booting kernel from USB on the internet but I didn't
see any help. :(

Thank you for answer

Re: [U-Boot] [T-Engine] UBoot configuration for T-Engine/SH7727 MS7727CP02 DevKit

2008-09-12 Thread thaoth 

Hi Yoshihiro Shimoda,
* Strategy 1:
I add usb_cpu_init following your tutorial:
int usb_cpu_init(void)
{   
*STCBR3 = 0x18;
*SRSTR = 0x18;  
cpu_wait_ms(50);
*EXCPGCR = 0x21;//0x28;
*PECR = 0x1500;
cpu_wait_ms(50);
*SRSTR = 0x00;
*STCBR3 = 0x00;

return 0;
}
now, I plug the USB2.0(mass storage) into board T-Engine(sh7727) and run
command usb start, the u-boot can't get decription of usb device with the
errror following:

New Device 1
usb_control_msg: request: 0x6, requesttype: 0x80, value 0x100 index 0x0

* Strategy 2:
I add usb_cpu_init the same strategy 1, I only add instruction printf(ep
= %x\n,ep); into function usb_set_maxpacket of usb.c
int usb_set_maxpacket(struct usb_device *dev)
{
.
...
ep = dev-config.if_desc[i].ep_desc[ii];
b=ep-bEndpointAddress  USB_ENDPOINT_NUMBER_MASK;  

printf(ep = %x\n,ep);   
.
..
}
in this strategy, when I run command usb start, now I can get information
of USB device:
Manufacturer
Product  USB_DRIVE
SerialNumber 00106886
2 USB Device(s) found
   scanning bus for storage devices... usb_control_msg: request: 0xFF,

0x0
usb_control_msg: request: 0x1, requesttype: 0x2, value 0x0 index 0x2 length
0x0
1 Storage Device(s) found

I don't know what is problem?why when I add instruction  printf(ep =
%x\n,ep);, u-boot can get description of USB device
*Strategy 3:
I try replace the insctruction printf(ep = %x\n,ep); with one of these
instructions
- instruction 1: wait_ms(10)
- instruction 2:void * pointer = ep;
- instruction 3: printf(ep = %x\n,ep);
But the result when run command usb start the same strategy 1, I can't get
information of USB2.0(mass storage)


Can you help me to resolve this bug?
Thank you very much for your supports!

 I think that 0x21 is correct value of EXCPGCR for your board.

 (96MHz / 2 = 48MHz)
 
 And I used my board, I set 0x1500 in PKCR.
 I don't understand PKCR - Port control register so I don't know correct
 initialize value of this register.
 
 0x1500 = 0001 0101  
 - PK6 is port output
 - PK5 is port output
 - PK4 is port output
 I don't know this value could be set for my board - TEngine/SH7727.
 
 Oh, I am very sorry. This is PECR.
 This setting enable USB1_pwr_en and USB2_pwr_en pin.

Re: [U-Boot] [T-Engine] UBoot configuration for T-Engine/SH7727 MS7727CP02 DevKit

2008-09-11 Thread thaoth 

Hi,

 
 Following your instruction, I did
 int usb_board_init(void)
 {
 printf(usb_board_init\n);
 
 outw(0x18, STBCR3);
 outw(0x18, SRSTR);
 udelay(10);
 
 outw(0x28, EXCPGCR);
 udelay(10);
   
 outw(0x00, STBCR3);
 outw(0x00, SRSTR);
 return 0;
 }

 These registers are 8-bit width. So please use outb() macro.
They are the same. It is still problem.

 I am sorry, my explanation was short. This EXCPGCR value was for an
 another board.
 In the case of your board, it may be necessary to make it a defferent
 value.
As specification of SH7727, value of EXCPGCR is 0x28 and this means


The SH7727 has an on-chip USB interface (USB) which requires a fixed 48-MHz
clock source.

The extend clock pulse generator (EXCPG) generates a divided clock from the
internal clock (Iφ),
the bus clock (Bφ), or the external clock (UCLK).

Because the clock sources, which can be a candidate to be used by EXCPG,
vary from CPG
setting or external clock source, user of SH7727 must adjust the divided
clock, carefully to be 48
MHz.

* Bits 5 to 3—Clock Select (USBCKSEL2 to USBCKSEL0):
000: Peripheral Clock (Pφ) (Initial value)
100: Internal Clock (Iφ)
101: Bus Clock (Bφ)
110: External clock (UCLK)
***: Another value Reserved (setting prohibited)

* Bits 2 to 0—: Divider Select (USBDIVSEL2 to USBDIVSEL0):
000: 1/1 - Dividing Ratio Selection
001: 1/2
010: 1/3
1**: Internal clock (Iφ), bus clock (Bφ), external clock (UCLK) halted

0x28: 00101000 - 00 101 000 - 
* 101: Using bus clock
* 000: Dividing Ratio Selection is 1/1

I know 
* Internal clock: 96Mhz
* Peripheral Clock: 24Mhz
* CPU Block: 144Mhz

http://www.nabble.com/file/p19449833/a.JPG a.JPG 

Please let me know the correct value of EXCPGCR ? Is 0x28 correct initialize
value of USB clock?

 And I used my board, I set 0x1500 in PKCR.
I don't understand PKCR - Port control register so I don't know correct
initialize value of this register.

0x1500 = 0001 0101  
- PK6 is port output
- PK5 is port output
- PK4 is port output
I don't know this value could be set for my board - TEngine/SH7727.

I am appreciating your helping :)

Re: [U-Boot] [T-Engine] UBoot configuration for T-Engine/SH7727 MS7727CP02 DevKit

2008-09-02 Thread thaoth 

Hi Nobuhiro Iwamatsu,
Now I'm porting USB on board T-Engine(SH7727)
- My configure following :
#define CONFIG_CMD_USB
#define CONFIG_USB_OHCI_NEW 1
#define CONFIG_USB_STORAGE  1
#define CFG_USB_OHCI_REGS_BASE  0x04000400
#define CFG_USB_OHCI_SLOT_NAME  s3c2400
#define CFG_USB_OHCI_MAX_ROOT_PORTS 15
#define CONFIG_DOS_PARTITION1
#define CONFIG_SYS_CLK_FREQ 
#define TMU_CLK_DIVIDER 4   /* 4 (default), 16, 64, 256 or 1024 */
#define CFG_HZ  (CONFIG_SYS_CLK_FREQ / TMU_CLK_DIVIDER)
- And in lowlevel_init.S, I change USB clock following:
UCLKCR_A:   .long   0xA40A0008
UCLKCR_D:   .long   0xA5C0
mov.l   UCLKCR_A,r1
mov.l   UCLKCR_D,r0
mov.w   r0,@r1
- When I'm starting board with above configue, I  see the led of USB device
is blinking. Then I run command usb start, the led turn off and u-boot
don't find any USB device, with following logs:
DEBUG: OHCI controller usb-s3c2400 state

- I don't know what is wrong in my configure, I think the
CONFIG_SYS_CLK_FREQ and CFG_HZ is incorrect and I can't start USB device,
and clock which I control in lowlevel_init.S following:
FRQCR_A:.long   0xA415FF80  /* FRQCR Address(Frequency Control 
Register) */
FRQCR_D:.long   0x1103  /* I:B:P=8:4:2 */
Can you help me about this problem and  tell me about any other wrong things
in my configure? why the led turn off when I run command usb start?

thanks

 Hi,

 Hi Nobuhiro Iwamatsu,

 1. Clock frequency of board.

 #define CONFIG_SYS_CLK_FREQ 
 #define TMU_CLK_DIVIDER 4   /* 4 (default), 16, 64, 256 or
 1024 */
 #define CFG_HZ  (CONFIG_SYS_CLK_FREQ / TMU_CLK_DIVIDER)

 I don't understand how to set CONFIG_SYS_CLK_FREQ value. From T-Engine
 support, they said clock frequency of board is 144MHz.
 
 
 Please set outside clock to CONFIG_SYS_CLK_FREQ.
 

 2. Cross compiler tool chain : GCC vs T-Engine toolchain
 There are two tool chains
 -
 http://www.superh-linux.org/archive/bsp/sh7721_se/toolchain_sh3_gcc4.2.tar.gz
 support elf32-sh-linux target.
 - Tool chain from T-Engine forum support elf32-sh-tkernel
 Using both cross compilers, we could turn on LED on debug board by
 setting
 correct value LED_A and LED_B value.

 3. ICE or JTAG debugger and LED debugging.
 I don't have these debug tools, and so hard for debugging.
 T-Engine/SH7727
 DevKit has debug board with 8 LEDs. I could turn on/off these LEDs by
 setting correct value to 0xA160 memory. But  C function turn on/off
 LED
 cannot work. For example

 int cpu_init(void)
 {
// Turn off LED 1 to notify cpu_init is called.
outw(0x00  0xFF, 0xa160);
return 0;
 }

 I don't know why it isn't called?
 
 I think that cpu_init is not carried out.
 I think that u-boot stopped on lowlevel_init function.
 

 Would you please give me your ideas? Thank you a lot.
 
 I will get T-Engine board ..
 Please wait.
 
 Best regards,
  Nobuhiro

Hi Nobuhiro Iwamatsu,

I have checked sequence initialization functions in sh_generic_init and the
problem is serial library cannot work correctly. The result is output to
console cannot display.

Regards.

Hi Nobuhiro Iwamatsu,

1. Clock frequency of board.

#define CONFIG_SYS_CLK_FREQ 
#define TMU_CLK_DIVIDER 4   /* 4 (default), 16, 64, 256 or 1024 */
#define CFG_HZ  (CONFIG_SYS_CLK_FREQ / TMU_CLK_DIVIDER)

I don't understand how to set CONFIG_SYS_CLK_FREQ value. From T-Engine
support, they said clock frequency of board is 144MHz.

CPU:   SH7727 144 MHz
Flash ROM: 8000 - 807F : 8 MB (64 KB blk x 128)
   8000 - 8000 : Monitor Area (64 KB)
   8001 - 8001007F : RomInfo Area (128 B)
SDRAM: 8C00 - 8DFF : 32 MB
   8C00 - 8C001FFF : Monitor  System Area (8 KB)

Could I set CFG_HZ to 144?
#define CFG_HZ 144
