Hi, I'm trying to get Linux (2.4.19) up and running on a BMW board (from Broadcom) with a 8245 processor. I'm using ppcboot 1.2.0. I've found that early_init() in setup.c does not return. Everything is ok up until the very end of early_init(). Something very basic must be wrong. I would be happy for some some pointers as to what this could be! Cheers, Jostein Pettersen

IMHO, the BMW support from Broadcom is wretchedly bad. At my former employer, I implemented my own BMW support and ignored the Broadcom code completely. This helped my disposition immensely. PPCboot 1.2.0 (or any version called "PPCboot") is pretty old. Did you get reasonably fresh code from Broadcom (if they have any)? Or is this the same BMW support that has been in the base for years? Broadcom released a number of variations on the BMW platform, including multiple CPCI cards and multiple pizza-box variations. It is extremely likely that your board doesn't match what is in the ppcboot/u-boot source in some crucial detail, e.g. clock speed. Some experimentation may be worthwhile. I spent a couple of years as "the" Linux (and U-Boot) guy for a company which used nearly every Broadcom board based on BMW (and Mousse, fwiw). I may be able to help you. Contact me off list if you'd like to arrange something. Thanks, John P.S. linuxppc-embedded is not the right list to ask about PPCboot/U-boot...try u-boot-users@lists.sourceforge.net instead... -- John W. Linville linville@tuxdriver.com
