Hi,
On our custom board we are experiencing some issue while booting Linux. Linux boot fails with a kernel panic and the error message: "Unable to handle kernel paging request at virtual address ".
See below for an example of the error:
It is not always the same virtual address the paging fails on and it changes on different boot iterations.
So far, as we use 8Gb RAM, we have adapted U-Boot and RTOS PDK memory configuration as documented in the Jacinto 7 DDRSS Register Configuration Tool: https://www.ti.com/lit/an/spracu8/spracu8.pdf?ts=1635504871631&ref_url=https%253A%252F%252Fe2e.ti.com%252F
Are there additional steps to take into account order to configure the memory properly?
I have seen the following e2e post: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/950628/tda4vm-tda4vm-how-to-config-mt53e768m32d4dt-3gb-ddr-on-tda4vm/3516412?tisearch=e2e-sitesearch&keymatch=ram_size#3516412 which highlights a couple more steps to take if the RAM has a reduced size compared to the EVM. Are there similar steps to take in case RAM size is increased?
For now, we have not modified any Linux or SDK memory map related configuration. What would be the required steps to do so in order to adapt to 8Gb?
Are there additional configurations to take into account which might cause this issue?
Thank you and Best Regards,
Max
