Ciaran,

The stock u-boot-0.4.0 release tarball works just fine for me with the following changes. Mileage may vary based on your configuration ... but here's the only changes I made for mine:

In include/configs/MPC8266ADS.h: Change CFG_FLASH_BASE to 0xFF800000 Change FLASH_BASE to 0xFF800000

In board/mpc8266ads/config.mk: Change TEXT_BASE to 0xFFF00000

If SDRAM initialization gives you trouble ... In board/mpc8266ads/mpc8266ads.c: Change CONFIG_PBI to 0

Set your switches to:

SW1: All on SW2: All on SW3: 1-on 2-on 3-off 4-off SW4: 1-on 2-off 3-on 4-off 5-on 6-on 7-on 8-off

You'll have to rtfm if you don't want to use the BCSR as the HRCW source or if you want to monkey with the PCI clocking options ;-)

BTW: PCI worked just fine with several different NICs.

Slan, --Scott

Hello all, I am a newbie to u-boot and I am trying to get u-boot0.4.0 to download to the flash on an MPC8266ADS-PCI development board. I managed to get u-boot0.2 on the flash and working as it should but unfortunately it needed fixed for the PCI features of the 8266. I have tried 0.3 and 0.4 but cannot get it to work. Both myself and some guys at Motorola have been trying for 4-6 weeks now to get u-boot & PCI up and running. Has anyone managed to get u-boot to work on this platform with PCI support enabled? If so, I would be greatful if could you mail the .srec to cd7@hw.ac.uk First of all I am using ELDK to cross compile the u-boot source which seems to work fine. The problem is that it doesn't seem to like the

Flash very much. I am using the Sharp type flash. I have tried the both the default configurations, with no success and also modified the following settings, also without much success.

1.) Within {u-boot}/include/configs/MPC8266ADS.h there are two choices for CFG_HRCW_MASTER depending on which JP setting you want to use - does anyone know which one is best to choose here?

2.) Also the settings for the CFG_FLASH_BASE default to 0xFE000000. From the MPC8266 user manual I noticed that the memory location this relates to

is for a 32M SIMM whereas I have 8M which starts at FF800000. I changed this to mirror the user manual and update also the CFG_BR0_PRELIM accordingly (0xFF801801).

3.) I have also played around with the {u-boot_dir}/board/mpc8266ads/config.mk file to no avail.

If someone out there has managed to get this working it would be great if you could either explain everything I need to do to get it blown to the flash on this type of board. Like I say I am a newbie to this and probably

need to plead ignorance, or b) have a working copy for an MPC8266ADS-PCI that you could send to me as I can't proceed past this point.

Any help is very much appreciated. Thanks Ciaran Doyle
