We have a P2020-MSC8516 AMC Combo board. Unfortunately the bootdelay was changed to 0 and we are not able to stop the booting of linux.
the mtd-partitions of kernel and rootfs are read-only. So we are not able to erase the partitions from the linux prompt. also the boot environment variables doesn't have a separate partition.
The board doesn't not have any jtag interface for p2020. Is there any way to erase the flash or change the boot environment variables.
The flash is a nor flash (s29gl512p) of 64mb.
