Hi!
I purchased a J-Link EDU Mini when I was in school; it was sometime around 2017. I was wondering if there are limitations on what MCUs it can connect to? I purchased an STM32H755ZI devboard which has a Cortex M7 and M4; it is unable to connect to them. I have two other devboards it can connect to, an NXP Kinetis K82 (CM4) and and NXP LPC55S69 (2x CM33). I tried connecting my EDU Mini to the H755ZI with both JTAG and SWD, on both the M4 and M7 at an interface speed of 100 kHz.
I took my H775 devboard to work and was able to connect to it using a J-Link PLUS Compact and was able to step through code with it. Edit: My day job embedded work and personal interests are different; I am not using my EDU Mini for any money-making endeavors.
My JLink EDU Mini is running the latest firmware, as far as I can tell. Serial Number and version information below. I've also attached terminal output. It tries several reset methods and fails at scanning the JTAG chain.
Thanks for any information you can provide!
