Hi @aviralgarg05 thanks for the rework. Although the proposed solution might work it might be limited by the available memory. I think the simplest and best way to boot a different image is to use `ioctl(fd, BIOC_PARTINFO, &partinfo)` to retrieve the partition offset. Once the partition offset is known the rom based `bootloader_mmap()/munmap()` routines can be used in the "startup" routine to verify correct header info. Also in the "startup" routine the `bootloader_mmap()/munmap()` routines can be used together with `memcpy()` to load the rtc, dram, iram. The approach can be similar to the method used in the esp-idf port of mcuboot (https://github.com/mcu-tools/mcuboot/blob/main/boot/espressif/port/esp_loader.c). -- This is an automated message from the Apache Git Service.
