using SEGGER JLINK with cubeprogrammerCLI

AbubakkarSiddiq · ‎2025-09-22

I'm trying to connect my STM32H743IGTX controller with JLINK using cubeprogrammerCLI. I am able to connect jlink with cubeprogrammer gui and able to flash. but when i tried using CLI it shows

-------------------------------------------------------------------
STM32CubeProgrammer v2.20.0
-------------------------------------------------------------------

Error: Could not connect to the J-Link/Flasher, Library not found !

im trying to use external flash using my custom loader file generated from cubeide.

the command i used is,
/home/STMicroelectronics/STM32Cube/STM32CubeProgrammer/bin/STM32_Programmer_CLI -c port=JLINK ap=0 sn=601003130 freq=4000 reset=SWrst -el /home/STMicroelectronics/STM32Cube/STM32CubeProgrammer/bin/ExternalLoader/XIP.stldr -w /home/project/build/test.hex 0x90000000 -v

Does it work without a custom loader?

Does the CLI work with an ST-Link ?

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

Or, if CLI is required, use ST-Link ?
