Hi all
this is probably a beginers question, but I am finding strange things
when booting with the BDI2000 on my mpc8548 CPU v2 board. I am using the
bdi config for rev2 silicon as shown below: Am i missing something?
;bdiGDB configuration file for SDH/SONET Gateway (MPC8548)
; based on configuration file for CDS8548 Rev.2 silicon
;---------------------------------------------------
; Move the L2SRAM to the initial MMU page (MPC8548 rev2 silicon)
WM32 0xFF720E44 0x0000001C ;L2ERRDIS: disable parity error
WM32 0xFF720000 0x60010000 ;L2CTL
WM32 0xFF720100 0xFFF80000 ;L2SRBAR0 (rev.2): map to 0x0_FFF80000
WM32 0xFF720104 0x00000000 ;L2SRBAREA0 (Rev.2)
WM32 0xFF720000 0xA0010000 ;L2CTL

Things look fine until the phys are initialized, then in stead of
printing the phy name rubbish id printed. in this case in stead of
"eTSEC" u-boot prints "invalid reserved".
When I inspect the memory which is supposed to contain the phy device
name with the BDI, on the CPU rev1 board I find the correct string in
memory but on the rev2 board I find arbitrary string.
Net: miiphy_register: added 'invalid reserved', read=0x1ffb2eac,
write=0x1ffb2e44
debug: dev name addr = 0x1ff90124
debug: phy id = 0xFC4B
invalid reserved: PHY is Vitesse VSC8211 (fc4b1)
This also results in meaningless info when running mii dump:
UBoot=> mii dump
0. (1140) -- er --
(fffb:1140) 0. 1- 0 = 4416
(fffb:1140) 0.129- 0 = 4416 <a[
(fffb:1140) 0. 1- 0 = 4416 �A�
(fffb:1140) 0. 1- 0 = 4416
(fffb:1140) 0. 1- 0 = 4416 ��x���aH
(fffb:1140) 0. 1- 0 = 4416
(fffb:1140) 0. 1- 0 = 4416 �|
(fffb:1140) 0. 1- 0 = 4416 ��1。 O
(fffb:1140) 0.63- 0 = 4416 ��_a(��� �?
(fffb:1140) 0. 1- 0 = 4416
Is this purely related to using the BDI or is the problem related to
other configuration items or simply CPU silicon related?
thanks for any input Hendrik
