Hi,
I am looking for a solution to allow a single Jlink Ultra+ to be able to switch between JTAG and SPI on a PCBA. Hope somebody can help me. Thanks in advance.
Currently, I have a SPI flash and a R9A uC on the same board. I am using a single Jlink to program the SPI directly as well as to issue 'JTAGLOAD' commands to the R9A. Both are donw through command line because I need to automate the functions. I have realised that if I were to perform JTAGLOAD commands first, followed by SPI programming, Jlink will prompt a message as attached. If I click 'Yes', the SPI programming will proceed without issue. Only thing is this will cause a need for operator intevention, which is not desired.
If I were to do the SPI programming followed by the JTAGLOAD commands, the commands will fail without any prompt for switch.
So I wonder if there is any command (line) that I can use to somehow switch between the 2 interfaces?
Thanks lots for your valuable solutions.
