AM2434: Uniflash with Custom Flash failing to load appimage

Part Number: AM2434
Other Parts Discussed in Thread: SYSCONFIG, UNIFLASH

Hi Experts,

We are currently using 8.05 version of SDK in our application FW. In the 8.05 version of SDK, configuration is generated by SysConfig from the options provided in the SysConfig Flash Module during the build process. We want to have a flash driver that supports multiple flash device which are pin to pin compatible and are an alternate part number to IS25LX256-JHLE Flash device. This would mean parse the SFDP parameters during bootup and configure the flash accordingly. I was able to do this successfully by using certain functions from the ospi_flash_diag example project and also making some changes to flash driver.

However, When I make a similar change to flash driver in uniflash project as we require to load our SBL and application through UART. I am having some issues.

I can successfully send SBL image but application image has some issues.

Could you please help?

Thanks,

Prithvi

Hi Prithvi,

From the screen capture, it seems the SBL is written to the flash OK. It means the updated flash driver is working properly. The issue is with sending the application image via UART. It is part of the undated uniflash project. Have you tested the same updated uniflash project with other application image like hello world? Just to make sure it is not the issue caused by the application image.

Best regards,

Ming

Hi Ming,

I get the same error even when I load our release/production version of application image which is tested and working without issues.
