Colibri iMX6, custom WEC2013 based on Toradex BSP 1.1.
Toradex Ce Libraries 1.9.3609 in ARMV7 debug mode.
I use your demo code from UpdateLib_Demo.c only the bootloader file path is modified. Upd_Restore returns 0 (= failure) inside updateIMXBootloader(). Using the same code and same eboot.imx but linking the *.lib from 1.8.3509 the bootloader can be flashed.
nk.bin can be flashed with 1.9.3609, but in my console application after Upd_Deinit I get an Access violation exception in msvcr110d.dll.
