Hi, I'm using an Cortex-M3-based chip called EFM32G from Energy Micro, with a an Energy Micro Dev Kit as my J-Link board. These boards are supposed to be fully licensed to use with authentic J-Link software, and I have a valid Energy Micro serial number.
It works great under Windows, using Energy Micro's provided Simplicity Studio software. I assume that means my serial number is OK. However, when I use JLinkExe under Linux, I can read the flash and do other useful things, but not write to it (and testwspeed command also fails).
JLinkExe does report my hardware's serial number correctly.
Does anyone know what's going on here? Does anyone else have EFM32 experience under Linux?
