STM32U5A9J-DK OctalFlash Read failure

Go to solution

Hello,

 

I generated a project for STM32U5A9J-DK with STM32CubeIDE (v1.16.0). It doesn’t include the OctalFlash test code. So, I used the test codes in chapter "Octo-SPI FLASH in Regular-command protocol example" of attached AN5050.

The mounted OctalFlash is MX25UM51245G. With the program, the data output was shifted by one byte as below.

After I use the HAL_OSPI_DELAY_BLOCK, the pass rate becomes higher but still fails. Please help.

 

Thanks.

Hi @JKim.2 ,

 

For DTR read, I used the delay block in order to fine tune the data-received sampling clock. Also the delay block role is used to apply a phase-shift to the clock or DQS signal when reading from external memory. You can find in the attachment file a project with successful DTR OCTAL Read.

KDJEM1_0-1726132141796.png

For more information for the delay block, I advise you to take a look at AN5050 Section 6 OCTOSPI and HSPI/XSPI interface calibration process.

Please let me know if your issue is solved or not?

 

Thank you.

Hi @JKim.2 ,

 

Could you please check the dummy cycle. Incorrect dummy cycles can cause data misalignment.

May this discussion Solved: External Flash downloader shift 1 byte in flash ar... - STMicroelectronics Community and this example BSP can help you.

 

Thank you.

Hi Kaouthar,

Thank you for the answer. I tried longer and shorter dummy cycles but still failing. How can I run the BSP on STM32CubeIDE?

Hello @JKim.2 ,

 

Thank you for updating post and come back to the community.

You can run the BSP example by open this example using STM32CubeIDE toolchain. Please take a look at UM2609.

KDJEM1_0-1725351565620.png

Also, I think OSPI_NOR_MemoryMapped can help you.

Do you observe the same behavior when you run these examples?

Thank you.

Hi Kaouthar,

I imported the project but it can't be compiled as below. How to solve those errors?

Hello @JKim.2 ,

 

Could you please try to download STM32CubeFW_U5 using STM32CubeMX toolchain as shown in the below figures/

KDJEM1_0-1725454504380.png

 

 

KDJEM1_2-1725454652056.png

Then, please try to open the OSPI example by following these steps:

KDJEM1_4-1725454986071.png

 

Could you please share your OCTOSPI configuration?

Hi Kaouthar,

The embedded software packages manager shows that the 1.3.0 STM32Cube MCU Package for STM32U5 is installed. I tried to install 1.6.0 from the local directory as below. It alerted "this package version is already available on current STM32CubeMX repository.". Is it fine? I opened the OSPI_NOR_MemoryMapped project again from file system. The compilation still has the same error message. The ioc file of the original project is attached for the OSPI configuration. The new project OSPI_NOR_MemoryMapped doesn't have the ioc file.

Best Regards,

Jeff

Hello @JKim.2,

The embedded software packages manager shows that the 1.3.0 STM32Cube MCU Package for STM32U5 is installed.

Please use the latest STM32CubeMX version 6.12.0 and click on Refresh button to see the latest version of STM32CubeU5 firmware

KDJEM1_1-1725524717617.png

I tried to install 1.6.0 from the local directory as below. It alerted "this package version is already available on current STM32CubeMX repository.". Is it fine? I opened the OSPI_NOR_MemoryMapped project again from file system. The compilation still has the same error message. 

I advise you to delete all STM32CubeU5 firmware versions and to redownload again using STM32CubeMx or from this link STM32CubeU5 - STM32Cube MCU Package for STM32U5 series (HAL, Low-Layer APIs and CMSIS, USB, File system, RTOS, TF-M - coming with examples running on ST boards) - STMicroelectronics .

If you want to use GitHUB please take a look at this post.

About  the OCTOSPI configuration, I noted that the device size is wrong: For 512Mbits=64MBytes, the Device Size must be configured in .ioc file at 26.

Which mode are you using DTR mode or STR mode?

Note that, Sample shifting (SSHT) recommended to be enabled in STR mode and disabled in DTR mode and Delay hold quarter cycle (DHQC) enabled in DTR mode and disabled in STR mode.

Are you doing a OCTA Read Mode (8READ, ECh) or OCTA DTR Read Mode (8DTRD, EEh)?

May this main.c and main.h can help for checking OCTOSPI configuration.

 

Thanks and best regards,

Kaouthar

Hi Kaouthar,

I installed the latest STM32CubeMX version 6.12.0 as you suggested. btw, both remove and install button on STM32CubeMX are disabled as below? How to remove all the MCU Package for STM32U5 Series?

Hi @JKim.2 ,

 

Click on STM32Cube MCU Package for STM32U5 Series to enable remove button. Then, click on Remove.

To install the latest version click on STM32Cube MCU package for STM32U5 series 1.6.0 version. Then, click on Install.
