[SOLVED] unknown entry point in jlink command file

mastupristi · April 8, 2022 at 11:10 AM

I work with RT1051 and I have a project contained and executed in RAM.
I wrote a command file to automate loading and execution:

Code

connect
sleep 10
r
sleep 100
loadfile "image/executable.hex"
sleep 10
setpc <ENTRYPOINT>
sleep 100
g
sleep 100
exit

Display More

Every version I make <ENTRYPOINT> can change, forcing me to introspect the produced binary.

To automate this aspect as well, how could I do it?

For example, is it possible to pass parameters from JLink command line to CommandScript? Or is it possible to declare variables inside the script that I would populate by reading the content of a specific memory location (the address of the ResetISR inside the vectors)? Or are there other methods I haven't considered like JlinkScripts?

best regards
Max

Hi Max,
There is no such feature available.

You could however work around this by adjusting the command file via some kind of script file (e.g. Python)
- Have a template command file containing the <ENTRYPOINT> place holder.
- The script parses the template and creates a copy with the <ENTRYPOINT> placeholder replaced by the actual address and calls J-Link Commander with the adjusted script file.

You could also get your hands on the J-Link SDK and write your own applications, adapt J-Link Commamder to your needs, …
