SK-TDA4VM: kernel panic - not syncing: no working init found.

Can you check the Kernel command line and see if the root parameter is populated?

The kernel command line should be printed in the logs before you see the panic.

Regards

Karan

Hi Shilpa,

Can you confirm that the file system is in the SD card? On the SK board can you make sure that the rootfs is written properly?

Regards,

Keerthy

In the sd card, inside rootfs there is boot, lib and usr folders.

Shilpa

There is no "root" in the Kernel Command Line, this is why the kernel is not able to load the file system.

[ 0.000000] Kernel command line: console=ttyS2,115200n8 earlycon=ns16550a,mmio32,0x02800000 mtdparts=47040000.spi.0:512k(ospi.tiboot3),2m(ospi.tispl),4m(ospi.u-boot),256k(ospi.env),1m(ospi.sysfw),256kt

Please create the SD card using the method described here.

Hello Karan,

Above link is for flashing default image into sd card using balena etcher tool right. I am confused how this can be used in my case as I was trying to build sdk using top level makefile which generates desired modules ,boot files and the command they gave to copy to sd card was using make install.

Regards,

Shilpa

Shilpa,

You can create the balena etcher card once. Then if you want to change the dts or the kernel driver code then you can use the EVM SDK:

https://www.ti.com/tool/download/PROCESSOR-SDK-LINUX-J721E

Do the changes in the source code under: $PSDK?board-support/linux*

cd .$PSDK/
make linux

Edit the $PSDK/Rules.make file to point DESTDIR to /media/$USER/rootfs

Basically the rootfs partition of the SD card created using Balena etcher. This should let you boot custom kernerl/dtb.

Regards,
Keerthy
