The *.stldr file generated by MX25LM51245G_STM32L4R9I-DISCO (@ ST-LINK Utility 4.2.0.0) can't work for STM32L4R9I-DISCO device. Please give me some advices. Thanks.

The *.stldr file generated by MX25LM51245G_STM32L4R9I-DISCO (@ ST-LINK Utility 4.2.0.0) can't work for STM32L4R9I-DISCO device.

Step1. According to the readme.txt in the directory of "C:\Program Files (x86)\STMicroelectronics\STM32 ST-LINK Utility\ST-LINK Utility\ExternalLoader\MX25LM51245G_STM32L4R9I-DISCO", The detail is as follows:

@par Example Description

This an example of an external loader of MX25LM51245G flash memory for STM32L4R9I-DISCO.

This loader can be used with STM32 ST-LINK Utility and STM32CubeProgrammer.

@par Hardware and Software environment  

 - This example runs on STM32L4R9xx devices.

 - This example has been tested with STMicroelectronics STM32L4R9I-Discovery

  boards and can be easily tailored to any other supported device 

  and development board.

@par How to use it ? 

 - Place the folder "MX25LM51245G_STM32L4R9I-DISCO" under the following path inside the STM32L4 Cube firmware package  "STM32Cube_FW_L4_Vx.y.z" folder:

  STM32Cube_FW_L4_Vx.y.z\Projects\STM32L4R9I_DISCO\Examples\OSPI

 - Open your preferred toolchain 

 - Rebuild all files and load your image into target memory

 - After build, the loader should be displayed in the external loaders window, ready-to-use.

Step2. Add Existing project of MX25LM51245G_STM32L4R9I-DISCO by using the EWARM 8.22.1,then rebuild all files.So the 

*.out file will be generated, then rename to *.stldr and copy to the directory of "C:\Program Files (x86)\STMicroelectronics\STM32 ST-LINK Utility\ST-LINK Utility\ExternalLoader\"

IAR Configuration

Step3. When downloading MenuLauncher-STM32L4R9I-Discovery_V1.0.0.hex through ST-Link Utility 4.2.0.0,the error is as following:

23:49:29 : ST-LINK SN : 0678FF504955857567011028

The default MX25LM51245G_STM32L4R9I-DISCO.stldr (156KB) provided by ST can work well. So I suspect that bug has existed in the source code of MX25LM51245G_STM32L4R9I-DISCO.

ST'ers, would you give the solution for solving the issue? Thanks.

There's not much presence from ST here, this is primarily user-driven forum.

You might want to use the support website https://my.st.com/ols or contact ST directly.

I'm open to reasonable offers, but I'm not here to carry other peoples water. Resolving this will take time, effort and resources.

ST's code also say the 512 Mbit device is 32MB, rather than 64MB

@Community member​ 

I‘ve got it. Thanks.

According to the datasheet of ​MX25LM51245G , the size of Flash is 64MB, rather than 32MB.

The *.stldr provided by ST (default) is only for 32MB external loader, perhaps because of artificial constraint. :confounded_face:

[Tesla DeLorean]

Honestly I think this has more to do with the lack of thorough testing, and attention to detail.

[s m]

Has anybody found a solution for that problem?

[Tesla DeLorean]

Yes, have several working loaders, really need hardware in hand, super hard to do blind.​
