Hello,
I am trying to use a j-link plus to flash my cypress proc CYBL10563. I find that it is erasing the bootloader I have previously loaded even though I am not writing anywhere near that address.
In the J-Link Server GDB output, you can see reads done near 0x00 that contain data, after loading, those values are all 0.
This is preventing me from being able to flash my application using J-Link onto my cypress PRoC and have it run, as the bootloader have been removed.
Any ideas or help would be greatly appreciated. We have several J-Link Plus and Base's and are looking to get this working so we don't need to keep using the MiniProg3.
