Facing an issue while creating external loader for Nucleo-G491

[VPana.1]

Dear @Tesla DeLorean and @KDJEM.1 

I am using NUCLEO-G491RE board and i want to create external flash loader for W25Q64JVSSIQ QSPI flash memory. I used external loader files from Github and build the .stldr file and placed in CubeProgrammer. when i try to read from 0x90000000 location, i am getting read failure error. I used the below path to create external loader for W25Q64JVSSIQ QSPI flash memory,

https://github.com/STMicroelectronics/stm32-external-loader/tree/contrib/Loader_Files/other%20devices

Driver code is working fine since I am able to see the data in memory mapped mode with test code provided in the github link.

But, when create a external loader using github files and placed .stldr file into cubeprogrammer and working on read/write/erase and these operations are failing.

Could you please check my project and do needful. PFA for my loader project

Thanks

Dear @Tesla DeLorean ,

 

Thanks for your quick feedback. I've tried with the above mentioned option and still read, erase and write operations are failing.

I am seeing Init function fail when i set  log level to 3

Below is the reference screenshot

I'll have to double check. Typically mine will fail Init() if the devices don't report as expected. What does READ ID report in your application space BSP/CSP implementation?

Hello @VPana.1 ;

 

Could you please check the dummy cycle number and the hardware connection.

I recommend you referring to MOOC - External QSPI loader how to - YouTube and get inspired to check your configuration.

 

Thank you.

Hi @KDJEM.1 ,

Thanks for your feedback. I am exactly following the same as mentioned in the MOOC.

Using 6 dummy cycles for MemoryMappedMode()
