Syswrite0 is mostly on semihosting debugging. Get debug tools
Thanks man.
I also found it
now time to check if I can make it work
You can use advance debugging tools like Ozone debugger that will allow you to do instruction tracing. Just note that you need J-Link debugger to use these tools. We’ll cover such debugging topics in upcoming EH events
jlink is expensive 🤧
i know, but do not buy the cheap chinese version, you’ll waste your money. I tried many of them and they never really work, negative reliability.. if you don’t have access to jlink but use an stm32 you could try stlink, they are cheaper and good for stm
comes built in with nucleo board
but saw there are some firmware to turn stlink into jlink
Haven’t tried that
that should be enough.. i wouldn’t recommend to reflash a tool unless you have some spare time to debug it or for learning purposes.. a tool should be something you can trust, and hacking it is a miss and hit
miss or hit

I think you’re talking about jlink-ob firmware to be used with stlink relash utility to convert on board stlink to jlink
it sound great. try it, if you want 😉
have you tried it before?
yes
does it work like a jlink?
It’s the same as official jlink and works the same, compatible with all their advance debugging s/w
it’s flashing time
almost all aspects are the same incl. flashing time. The only thing is when it’s on-board jlink it’ll not be used with other micro’s apart from the one on the official board.
We can break it of from nucleo board
or is it limited by the particular MCU of that board ?
yes, if you break it then you’ll use as a normal stlink only
can’t use jlink firmware after breaking?
unfortunately no
but connections are all same

@umeshlokhande ozone is really good
it manages peripherals with good details
debugging is really wonderful
In a situation where basic debugging can’t help I found s/w like ozone very effective
it’s fast and responsive
I’d like to add a few more advantages, such as helping to locate dead code and identifying code hotspots in a larger codebase
I converted back into stlink
I saw JLink education which seems affordable to me
