[SOLVED] Open Flash Loader - error during connect - Error: Algo error: Cannot find struct "FlashDevice"

Hi Everyone,

we are using the brand new STM32L5 and at the moment we try to flash a external NOR flash via QSPI.
We have created our own open flash loader (OFL) an now we try to connect via J-Link.
Our OFL is based of our last project where it worked very well.
We add the device at the begin of the JLinkDevices.xml

<Device>


 <!-- This entry will overwrite the existing device entry in the J-Link software, so that a custom flash algorithm is used for the internal flash -->


   <ChipInfo Vendor="ST" Name="STM32L562QE" Core="JLINK_CORE_CORTEX_M33" />


   <FlashBankInfo Name="QSPI Flash" BaseAddr="0x090000000" MaxSize="0x00400000 " Loader="ofl.elf" LoaderType="FLASH_ALGO_TYPE_OPEN" AlwaysPresent="0"/>


 </Device>

But if we try to connect the following error is occur:

Connecting to J-Link via USB...O.K.

****** Error: Algo error: Cannot find struct "FlashDevice"


No valid device has been selected.

We have created a release version of the OFL without optimization. We can find the struct "FlashDevice" in our map-File.
Any ideas?
J-Link version is 6.44h.

Best regards and thx

Hi Nino,

thanks for your answer.
I have added the file. But I think this is not the problem.
Without my device entry in the xml file, jlink is connecting to the internal flash from the MCU very well, so I think the xml file will be found.
I think the problem is in my created Open Flash Loader application but I can't find the mistake.

If I tried to change the Open Flash Loader to any application, the error was be changed to

****** Error: Algo error: Cannot find "PrgData" section.

So I think that my Open Flash Loader was loaded.

With my Open Flash Loader the error will be changed to
****** Error: Algo error: Cannot find struct "FlashDevice"

Or is it necessary to adjust my Linker script?

Thanks a lot

Best regards,

Simon
