Hi @chalu,
Sorry for the delay. This issue is caused by FDT relocation.
Please, run this command on your u-boot terminal to fix the issue:
Verdin iMX8MP # setenv fdt_high 0xffffffffffffffff
Verdin iMX8MP # saveenv
Saving Environment to MMC... Writing to MMC(2)... OK
Verdin iMX8MP # reset
These three commands will fix your issue.
For more information m, please refer to this thread: Support of rpmsg in TorizonCore on Verdin iMX8MP - #16 by hfranco.tx
Let me know if you have any questions.
Best Regards,
Hiago.
