RTOS/AM5728: SMP execution hangs

Tool/software: TI-RTOS

Hi,

I tried to modify our application to use SMP on the AM5728 Rev1.3B. I followed the instructions.

processors.wiki.ti.com/.../BIOS
processors.wiki.ti.com/.../Public_SmpBiosSlides.pdf
software-dl.ti.com/.../ccs_smp-debug.html

But the execution hangs up at:

ti_sysbios_family_arm_a15_smp_Core_resetOMAP5xxx_I()

According to the instructions in this case, I should wake up the second core through a gel script.

But I didn't find any hint how to do this.

Is there an example?

Thanks & Best regards

Daniel

Hi,

There is an existing SMP example on AM572x:

This is part of TI Processor SDK RTOS release.

Hi Eric,

Thanks for your reply.

I tried your suggestion, but I got the same problem with this.

It also hangs up at

ti_sysbios_family_arm_a15_smp_Core_resetOMAP5xxx_I()

Daniel,

My colleague and I tried SMP examples in the past and we also developed some SMP example for A15 RTOS drivers, we didn't meet such issue. Did you use PRSDK 5.3? I also asked our colleague for help.

Daniel,

Is the issue still pending? The example really should be working as is...
