Unable to flash IMXRT1050-EVKB

Hello!

I've been stuck trying to flash the IMXRT1050-EVKB using ARM-DS.

I'm trying to flash the standard blinky program using MIMXRT105x_HYPER_256KB_SEC.FLM programming algorithm included in the pack.

I've also tried to create my own .FLM file, but that also does not seem to work.

It shows that it's erasing and programming, but then the program does not blink the LED and the board is unresponsive until I put it in serial downloader mode and erase/reprogram it.

I know that the build .axf file is ok, because I can flash it using MCUXpresso. And then I can even debug it using ARM-DS.

What are some steps I can do to resolve this issue?
