I'm in the middle of development of custom bootloader for i.MXRT1050 family processor and I'd like to use 'Plugin image' functionality. So far I managed to invoke proper function described in manual :
typedef BOOLEAN (*plugin_download_f)(void **start, size_t *bytes, UINT32 *ivt_offset);
but booting of loaded image fails after return. My question is: exactly what values shall be returned in function parameters with respect to target image IVT ? Eg. *start should be the pointer to the very beginning of the image (eg. 0x80000000, where IVT starts @0x80001000) ?
