STM32CubeProgrammer J-Link External Loader download

colinmurphygc · ‎2024-11-12

I'm trying to interact with the external flash on the STM32H573I-DK, and having some issues. I'm using the `MX25LM51245G_STM32H573I-DK-RevB.stldr` external loader.

Using the J-Link, I can read the flash and erase sectors, but the program immediately crashes when I try to program a file. It works fine using the ST-LINK.

ST-LINK programming:

J-Link reading and erasing:

Programming using the CLI:

A segmentation fault suggests a software bug in STM32CubeProgrammer when handling J-Link with this specific setup. STM32CubeProgrammer CLI installation may be corrupted. Try to run STM32CubeProgrammer with --verbose to get more detailed logs.

This happens with both the GUI and the CLI, but there's nothing to show/report with the GUI as it just crashes.

I have ran with the highest verbosity, but the output is not nearly as verbose as it is using the ST-LINK connection. I've included snippets for the failed download and for a succesfully erase of a couple of sectors of the external flash.

@colinmurphygc If you have a genuine J-link - while ST is working on a fix, you can program the flash with Segger J-Flash software. Segger developed "universal" loader for QSPI memories. User only has to select the pinout of the QSPI memory, then the loader automatically detects the model and size of the flash chip and does its magic.

> If you have a genuine J-link - while ST is working on a fix, you can program the flash with Segger J-Flash software.

If I might ask :
Does "genuine" in this context mean that ST-Links converted to JLinks with Segger's firmware are not supported ?

colinmurphygc · ‎2024-11-13

Thanks for the tip about the Segger J-Flash. I will look into this as a solution if ST confirm this CubeProgrammer issue is not caused by a user error on my side.

The GUI does produce a log error file; if it is of use I can send the full copy. I've included what looks relevant:

# C  [libCubeProgrammer_API.dylib+0x13780e]  ST_LINKInterface::DisableWDGRST(TargetInterface*, ST_LINKInterface*, bool)+0x2e

If this is your case, please try to run J-Flash on it and see if it complains. I haven't tried. Segger's "universal loader" works well with a real J-Link.
