TMDS243EVM: Working with ospi from RTOS application

Hi Yury,

There is no limitation as such that the Flash driver doesn't work for RTOS environment. Can you please give more details on the exact usecase? Because some of the APIs like Flash_write and Flash_erase are by design blocking. Let me know what exactly is the application trying to do.

Hi Anand, 

Thank yoy so much for the reply. I simply copied the contents of the ospi_flash_io example into the hello_world_main RTOS example function. Pre-enabled everything in syscfg. But for some reason the ospi tests do not pass.  If you say there no problem, I will try to investigate this issue further. 

Okay Yury, 

Can you let me know what is the exact point of failure? Like is it during the flash_write, or erase, or readback?

Hi, Anand Mahadevan SS! Sorry for the late reply. The problem during the flash_write.

I found a solution to the problem. It is to change the access rights in the Memory protection unit. Thank ypu so much!

Thank you for the update, Yury. I hope I can close this thread now.
