Beagleboneblack and latest SDK PSP 04.06.00.11

Hi,

Im working on a project based on the beaglebone black board and thus use a bbb. I wanted to use the latest sdk for this but even though the releasenotes indicates support I'm not able to find it.

I cloned the http://arago-project.org/git/projects/?p=linux-am33x.git and checked out the v3.2-staging branch and the mentioned sha1-id (d5720d33bc7c434f9a023dbb62c795538f976b7a).

I built the uImage on a more or less pure am335x_evm_defconfig

Booting the board yields

[    0.869246] Board name: A335BNLT
[    0.872627] Board version: 0A5A
[    0.875904] SKU: ������
[    0.878454] Could not detect any board, falling back to: Beaglebone (< Rev A3) with no daughter card connected
[    0.888915] The board is a AM335x Beaglebone < Rev A3.

Looking into the board-am335xevm.c I can find no traces of bbb support. What am i missing or doing wrong here?

Best,

/Tor

    Ok, the log output above was captured from a build on the wrong branch. (But the symptoms are still the same.) The correct log dump should be:

    [    1.010345] Board name: A335BNLT
    [    1.013732] Board version: 0A5A
    [    1.016998] SKU: ������
    [    1.019561] The error message above indicates that there is an issue with
    [    1.019561] the EEPROM or the EEPROM contents.  After verifying the EEPROM
    [    1.019561] contents, if any, refer to the am335x_evm_setup function in the
    [    1.019561] arch/arm/mach-omap2/board-am335xevm.c file to modify the board
    [    1.019592] initialization code to match the hardware configuration

    Some further digging. Downloaded the am335x-evm-sdk-src-06.00.00.00.tar.gz source and this indeed supported the bbb. Turned out that there where some 36 more patches applied to that code base then what is mentioned in the PSP release notes http://processors.wiki.ti.com/index.php/AM335x-PSP_04.06.00.11_Release_Notes

    So it seems that i can stop this monologue then ;)

    Hi Tor Kill,

    I am currently working on the BBB since I need to use Linux kernel 3.2 version. I also downloaded the am335x-evm-sdk-src-06.00.00.00.tar.g. But I could not find the things mentioned within this ladd00.triumf.ca/.../AM335x-PSP-User-Guide.pdf inside the am335x-evm-sdk-src-06.00.00.00. Actually I need to work on EDMA example within the PSP. But I could not find edma_test.c or edma_test.ko within the am335x-evm-sdk-src-06.00.00.00.

    You have mentioned about the "36 patches". Is it related to this? If it is related, please mention the location as well.

    Thanks,
    Vishwa
