Tool/software:
Hello Team,
I am working on AM335x based custom board bring-up activity. I am using 5.10 linux kernel from this link.
I configured dts file as per our custom board schematic and used tisdk_am335x-evm_defconfig as a base configuration.
I enabled early-printk related settings using menuconfig and certain drivers related to mmc.
I used rootfs and uboot image from old 3.2 kernel as it was already developed and available for that board.
My goal is to upgrade kernel and rootfs for my custom board to 5.10 version keeping uboot as it is from old kernel 3.2 version
When I try to boot my new kernel with new dtb file, booting halted at below point.
I am suspecting that kernel not able to read dtb file as there are no any logs related to pinmux.
Also no any mmc / usb device related log is found. Detailed log is attached with this post.
Please help me to root cause this issue.
[Note :There is no any h/w related issue as board is currently running perfectly with linux 3.2 kernel version ]
