Hi there,
I am trying to use a j-link EDU mini to flash to an Infineon TLE9879QXA40 BLDC shield with updated code from microvison. However as seen in the pictures attached i keep getting the error of no cortex-M SW device found. Have tried using JTAG and SW and neither work. With JTAG i can get to the point where it says reset error, but i have no clue what that means?
I probably am missing somehting super easy but i have never used a jlink before and never flashed a device so am quite lost.
Thank you in advance for any help.
