PROCESSOR-SDK-AM62X: R5F memory errors under kernel 6.12.13-ti

Part Number: PROCESSOR-SDK-AM62X

Tool/software:

Hello,

I'm running the AM62x dev board with Linux kernel 6.12.13-ti. The system comes up fine but I'm seeing these errors when the R5F core is being initialized at boot time:

platform bus@f0000:bus@b00000:r5fss@78000000:r5f@78000000: found no memory resource for atcm

platform bus@f0000:bus@b00000:r5fss@78000000:r5f@78000000: failed to get internal memories, ret = -22

k3_r5_rproc bus@f0000:bus@b00000:r5fss@78000000: k3_r5_core_of_init failed, ret = -22

k3_r5_rproc bus@f0000:bus@b00000:r5fss@78000000: k3_r5_cluster_of_init failed, ret = -22

k3_r5_rproc bus@f0000:bus@b00000:r5fss@78000000: probe with driver k3_r5_rproc failed with error -22

Prior to kernel 6.12.13-ti, I was running kernel 6.6.58-ti and was not seeing those errors. I also saw those same errors in what appears to be one of your CI/CD tests running 6.12.13 kernel too.

TI Linux CI/CD Snapshots

Any idea what those errors are pointing to, and whether or not this was fixed in a later kernel release? Thanks.

    Hello Ayman,

    We are still working on porting all of our code to Linux kernel 6.12. We are almost done, and we will release AM62x Linux SDK 11.0 sometime in the next month.

    I would expect 6.12.13 to NOT work properly, since the latest patches to the Linux R5F remoteproc driver were added 6 days ago, well after 6.12.13.

    It looks like the latest CICD boot logs are attaching to the DM R5F just fine.

    Please keep in mind that we will not be able to support questions about ti-linux-kernel-6.12 before the SDK 11.0 release, since we are still actively porting code and squashing bugs.

    Regards,

    Nick

    Hello Nick,

    Thank you for the quick response. We will wait for the next SDK and kernel release.
