LS1021a kernel panic

jagrati_chaudhary — Wed, 29 May 2024 18:15:58 GMT

i upgraded mu ls1020a based device from kernel 4.1.35 to 6.1.55 using LLDP extracted kernel and meta tool-chain and used the old device tree source to build new dtb file for new kernel as it is same custom hardware which use NAND flash .after writing new uImage and new device tree to ram using tftpboot i am getting kernel panic issue. I am going to add all the kernel log dts file and u-boot env setup for reference.I build the new kernel using old 4.1 kernel .config file. Attached config file also.

here is the u-boot environment.
