nrf_dfu_mbr_init_sd reboots

[palavrov]

I got permanent device reboot due hardware exception when come to this call:

Nordic-Thingy52-FW/external/sdk13/components/libraries/bootloader/nrf_bootloader_app_start.c

Line 57 in 99be6c1

err_code = nrf_dfu_mbr_init_sd();

The exception is because of bad memory access in SD132 v4.0.2 in function at address 00028720 - as it is closed source hex file cannot investigate further.

I tried to update SD132 to latest version 7.0.0 to check if it will work but the API differ too much and I give up at the end.

Could someone suggest me what I could do to avoid the bad memory access and the following reboot?
