Hey all,

I have worked on Freescale PPC boards a couple of times in the past and just got started using the blackfin. I have successfully gotten my pc setup to build a new kernel image for my blackfin, however when I load the new image on the board I get the following error.

Kernel panic - not syncing: Error: you are missing anomaly workarounds for this rev

I saw the same error when I downloaded one of the uImage file from blackfins website - eventually we found one on the website that did work, However I want to be able to compile the kernel my self - i assume it is some flag I must set or perhaps I will need to add a new board to the setup:

blackfin.uclinux.org/gf/project/uclinux-dist/frs/?action=FrsReleaseBrowse&frs_package_id=76

uImage-bf548-ezkit-2008R1.5-RC3 - worked

uImage-bf548-ezkit-2008R1-RC8 - worked

uImage_BF548-EZKIT - gives same error as i get on my compile

Paladin,

The cause of the panic is "Compiled for Rev 2, but running on Rev 0". Your BF548 is Rev 0, while your kernel is build for Rev 2.

You can set silicon revsion in: Blackfin Processor Options ---> Silicon Rev. However, 2009R1 kernel adds check for anomaly, so BF548 rev 0.1 and 0.0 are not supported - they are too old and having anomalies not easily to work around.

Hey Yi,

I could not find any prvious release of uClinux on blackfin website, I see that both version that work are compiled with the 2008 uClinux. I have downloaded the uClinux dist from source forge but it does not include Analog devices as a vendor. I am busy making the vendor files using 2009 as a sample. In case this does not work do you, or anyone else, know if and where the uClinux dist of from blackfin is downloadable?

Regards,

Paladin

all Blackifn support is through this website. fetching files from elsewhere (i.e. sourceforge) isnt going to work.

we've dropped support for BF54x-0.1 and BF54x-0.0 because they have hardware anomalies that cannot be worked around that boil down to random external memory corruption.

Hey Mike,

So does that mean the only real way forward is to get a new board? I have been able to compile the uImage using the linux kernel from 2008 (2.6.25 i think) however I am unable to add a number of applications (iptables, busybox, and havent look further but assume there are others that will fail) the build keeps failing. This build without any of the anomaly checking does boot - but without the applications it is kinda useless for us.

Thanks for the help,

Regards,

you should get a new board. i imagine if you simply edited the kernel source and removed the check in question, you'd get the same behavior as previous releases, but we cant really support random runtime crashes you may see after that.
