Hi,

The OSPI driver on the A72 QNX, is a QNX/Blackberry owned driver, and QNX/Blackberry should be contacted for recommendations, and/or their documentation referenced.

If question is related to updating the OSPI driver on the R5 in the TI PSDK RTOS release, please advise.

Regards,

Hi,

I only use nor-flash for system boot so I think you guide this issue.

I use eMMC device for QNX file system.

I found related source code about "Fls_NOR_s28hs512t.h" in /mcusw/mcal_drv/mcal/Fls/src/Fls_NOR_m35xu512.h but I can't use this code because this is not matched in /pdk_jacinto_07_01_00_45/packages/ti/board/src/flash/nor/device.

Could you check this one more?

Thank you.

Thanks,

There is related thread below, though in this case a related header file is present.

(+) TDA4VM: How to porting new OSPI Flash device in RTOS SDK - Processors forum - Processors - TI E2E support forums

If the Fls_NOR_s28hs512t.h, meets the needs for the nor flash device, it can be copied to the /pdk_jacinto_07_01_00_45/packages/ti/board/src/flash/nor/device, and development can proceed from there.

I can't patch below code because I don't have similar code in OSPI_v0.c.

I use SDK7_1. OSPI_v0.c

Hi,

Currently we do not have a patch to support cypress flash on SDK 7.1. Also, 7.1 is really old version, if that's not a huge effort, I would recommend you to migrate to latest SDK.
