boot up the linux kernel using vxworks boot ROM(split the elf )

hello, all: I am having trouble loading the image section of the elf file into ram (vmlinux) with the VxWorks bootloader. The vxworks bootloader could handle this by the bootloadmodule function(the vxworks lib function) using ftp to load the image and boot up the kernel.But now we want to

PowerMac vs. Intel for PowerPC Development Host

Brian, I think one advantage of using a mac with linuxppc as host (I use that @ home) is that you can use newer compiler/library versions a little bit more easy. I wasn't able yet to cross compile gcc-3.x for ppc on Solaris host, it worked however on the mac. Jaap-Jan brian.auld at adic.com

PPC405 UART

2003-02-20 Thread Samuel Ortiz
Hi guys, I'm currently working on a IBM ppc405 core based STBx25 board, and I'm trying to hack its UARTs. For those of you who are not familiar with these boards, the UARTs are almost standard ones. Their only difference with the typical 16550 ones is that they use 2 divisors instead of just

about filesize when copy from flash to ram

2003-02-20 Thread Jerry Van Baren
You are copying flash over top of your interrupt vectors, overwriting active code and crashing your system. Don't do that. Getting a load into the bottom of RAM (e.g. loading linux) is a delicate dance that u-boot does well, so use that function. You are not going to be able to do it with the

Support for MPC8265 PCI Bridge

Does Linux have support for the MPC8265 PCI Bridge? If so, how is it configured? What does the bootloader have to do? I am using U-Boot. Thanks, Don ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/

Dear friends, We are finalizing our project on a custom 8260 board and as suggested in many Linux HOWTO we are trying to move from NFS to ram filesystem. Actually we have burned the flash with both kernel and ramdisk images and modified the initial bootargs variable to indicate where to find the

I am working on bringing up Linux on a Motorola MGT5100 board. It's core is roughly a 603e, with lots of other devices on the chip. I am using an Abatron and have a question about really early boot. When the MMU is first turned and we are executing at 0xC-bazillion the Abatron can't read the

A $600 Dell 1.8GHz builds the 2_4_devel 440 kernel in 2m 45s. That's just great for our users. The x86's are getting cheaper and faster, too. However, we do use the native builds for some whacky packages (like X) that are never going to cross-build properly. } As an actual data point: my

Ah, if that's the case, another data point. The 2.8 GHz dual P4, with hyperthreading on (very important) and make -j 8 gives me a 1m 45s _devel tree build for the ebony. If the cache is warm it's faster but that's with a cold buffer cache. } I wasn't trying to compare fairly, mostly get the
