Hello community!
I have a STM32L476VG processor that once I program with an application, I'm unable to program the board using J-Flash again. If I use J-Flash lite OR a portable programmer, I'm able to reprogram the board. I'm using a copy'd version of a working application so I do not believe the pin configurations are incorrect.
If I use application A, I can reprogram indefinitely. If I use application B (which is a copy of A with some different commands), I can only program one time.
My segger output is:
Opening project file [C:\Users\mxoperator\Desktop\SVN Checked Out Stuff\SRW\bin\Debug\Firmware\SRW_SETUP.jflash] ...
