sharon, In the command you posted, there shouldn't be a comma between -readrange and 0x1007800.

So instead of using J-Link commander to read memory and save it to a .bin, I ended up using J-Flash. You can run J-Flash from the command line and create a command like this: JFlash.exe /min /wait -openprjProjectName.jflash -readrange0x…

However, it doesn't work as well in JLink or JFlash using the Release version. In JFlash I can't do anything, it says that the FRAM flash bank is overlapping with the in…

Ok thanks for that clarification. Turns out I found the info I was looking for in the JLink user manual, chapter 12 "Open Flashloader". It pretty much contains all the info that was on the wiki from what I recall seeing there before.

I am trying to use JLink Commander and/or JFlash with a JLink Plus probe to download the initial firmware to an MK61FN1M0VMJ12. Are elf files supported for JLink / JFlash? At the wiki page on JLink here: J-Link Commander - SEGGER Wiki it says that *.elf files are supported but when I try to open an ELF file in JFlash it says "Failed to create memory area from ELF file!" and when I try it with JLink Commander it says "File is of unknown / supported format." I had to create a flashloader for the e…
