Hi,

Try to build trunk for BF548-EZKIT, choose silicon revision 0.1. Got the following compile error:

arch/blackfin/mach-common/arch_checks.c:72:3: error: #error You are using a part with anomaly 05000448, this issue causes random memory read/write failures - that means random crashes.

Comment out the aforementioned conditional compilation block. Compile OK. Yet get kernel panic when booting the uImage.

Mike,

Thanks a lot for your time.

Maybe I asked a wrong question. Yes the anomly sheet indicates that there is no workaround available.

Then how should I configure the kernel in order to run the resulting image on a BF548-EZKIT?

I tried all the silicion revision options presented. None of them succeds (choosing "none" leads to compile error; choosing all others leads to "Kernel panic - not syncing: You can't run on this processor due to 05000448").

The 2008R1.5 release worked.

there is no configure option.  you need to delete the panic() line from the source code manually.  doing this indicates you understand that things may randomly crash at any time and there's nothing in software that can be done to "fix" it.

anomaly 448 wasnt known at the time of the 2008R1.5 release ... otherwise the panic() message would have been there too.
