Hi,
I'm working on K70TWR board with JLINK and CortexM connector.
Do I need to connect TRST from Legacy JTAG (pin 3) to CortexM connector pin 9 for that device ?
By looking at the schematic, I observed that the pin 9 is connected to K70 pin PTA4.
With a closer look at the schematic we can also observe that PTA5 is the TRST pin of the processor.
I'm asking these question because I'm able to to connect to the device and get CPU ID and see Cortex M4 displayed on JLink GDB server JTAG but I can't read and write to Flash memory.
Thanks.
