Problem booting P2020DS with SDK 1.4 images.

martindubé · ‎11-04-2013

Hi,

I'm using the QorIQ sdk 1.4 and successfully created the 'fsl-image-minimal' files. However, when I try to use them on a P2020DS, I get what looks like a hang when the kernel is booting. I've also tried nfs file system and I get the exact same problem. I tried SDK 1.3 and it also hang after "RPC: Registered tcp NFSv4.1 backchannel transport module", but I don't get the rcu_sched info messages however.

Here is the boot log:

=> setenv bootargs root=/dev/ram rw console=$consoledev,$baudrate

=> tftp $ramdiskaddr $ramdiskfile;tftp $loadaddr $bootfile;tftp $fdtaddr $fdtfile;bootm $loadaddr $ramdiskaddr $fdtaddr

P2020DS was removed since QorIQ SDK 1.2 release, the latest official SDK release for P2020DS is SDK 1.0.3 which could be downloaded from Freescale Linux SDK for QorIQ Processors, v1.0 and related releases.

martindubé · ‎11-05-2013

Hi,

Thank you for you prompt answer. So even if 'fsl-setup-poky' lists the p2020ds as a supported ppc machine, I must not assume that it is supported by the SDK?

I will give a try to the 1.0.3 SDK and the 1.2 SDK because I'd like to have to most recent (working) one.

Regards,

Martin

P2020DS has not been listed in SDK 1.2, 1.3 and 1.4 release notes.

martindubé · ‎11-06-2013

Thanks. I'm somewhat new to this and I didn't realize that P2020DS, P2020RDB and P2020 where 3 different things, so when I read "QorIQ Communications Processors Mid-Performance Tier: P2020, P2041/0, P3041" in SDK 1.4 release notes, I assumed that P2020DS was supported because P2020 is listed as supported.

I got it working with 1.0.3. Thank you again.
