Thamarai,
you need some patches to cross build gcc 3.x, but better
use crosstool, it includes the patches needed, both
for the compiler and glibc, and a script to build and
install everything.

gcc for ppc/predefined macros
I belive the problem is that you did not compile your cross-compiler correctly: $ ppc_7xx-cpp -dM /tmp/foo.h | grep pc #define __powerpc__ 1 #define __powerpc 1 #define powerpc 1 Make sure you do --target=powerpc-foo-linux when configuring gcc. Well, I have --target=powerpc-unknown-eabi, because I thought -linux is only needed for a full compiler with libc and all that. But you are probably right, the process for a cross-compiler described on penguinppc.org also has --target=powerpc-linux. Anyhow, except for this #define, the kernel compiled with the --target=powerpc-unknown-eabi gcc seems to work fine... -- Stefan Nickl Project Engineering Kontron Modular Computers Sudetenstr. 7 D-87600 Kaufbeuren Phone ++49/8341/803-294 ** Sent via the linuxppc-embedded mail list.

So, the question here is: do we need Rodolfo Giometti's patch to be applied to mpc8260 ATM driver? It is obvious that different set-up should be applied for mpc8260 ATM driver MPHY mode anyway...

You could just use a PCI network card to nfsroot a filesystem and get started, though. http://www.metrowerks.com/MW/Develop/Embedded/Linux/BSP.htm has an 8560ADS BSP for download...it probably has some drivers for on-chip peripherals included. BTW, you'll need the following patch to linuxppc-2.4 to fix outbound PCI mem cycles: = arch/ppc/platforms/mpc85xx_ads_common.c 1.3 vs edited = --- 1.3/arch/ppc/platforms/mpc85xx_ads_common.c Thu Jan 22 12:58:25 2004 +++ edited/arch/ppc/platforms/mpc85xx_ads_common.c Thu Feb 5 09:10:34 2004@@ -316,8 +316,8 @@ pci-piwar2 = 0; pci-piwar3 = 0; - /* Setup 128M outbound mem window @ 0xe000 */ - pci-potar1 = 0x; + /* Setup 128M Phys:PCI 1:1 outbound mem window @ 0xe000 */ + pci-potar1 = (MPC85XX_ADS_PCI_LOWER_MEM 12) 0x000f; pci-potear1 = 0x; pci-powbar1 = (MPC85XX_ADS_PCI_LOWER_MEM 12) 0x000f; pci-powar1 = 0x8004401a; /* Enable, Mem R/W, 128M */ -Matt ** Sent via the linuxppc-embedded mail list.

Interrupts on PPC 405Gr

I was passing it 5, which is the IRQ I wanted setting. When I changed the IRQ number to 30 it worked! I'm not sure if this is a screw up on my part for not passing the correct value in the first place, or an error in the Timesys kernel (surely the number passed in should be the IRQ required, not the bit position in the UIC registers). It's your error, just think what you have to pass to request_irq if you want to hook UART0 interrupt... IRQ5 - is _external_ (to the chip) interrupt line and NOT an interrupt number. _All_ UIC interrupts are external to the core (but not all of them are IRQx lines).
