TDA4VM: How to unmount Nor flash in the FLS driver of MCAL？

Thanks for posting your question to TI processor's E2E forum. The expert assigned to this thread is out of office due to public holidays in India today. Please expect a response by the end of this week.

Hello,

OK, thanks

Hello,

Sorry for the delay. Could you please explain more background of this scenario ? Which flash you are trying to un mount and mounting another flash? Could you share the errors encountered ?

Hello,

I need to load and unmount the same NOR flash. After the MCU reads the image from the NOR flash, I need to unmount it and then mount this NOR flash on the SOC. This is exactly what your sample code provides, except that I now need to convert the ospi driver from PDK to MCAL on the MCU side.

Hello Gary ,

I don't understand mount and unmount here, The code that you are trying is to integrate and leave the OSPI in legacy mode. This is generally used when we are booting HLOS from OSPI. So once the MCU R5 reads the required images from OSPI it will leave the OSPI in legacy SPI mode so that linux can configure it in it's own way and can read the OSPI if required. Is that what you are trying to do ?

and also i think we have integrated this in MCUSS DEMOS of can boot app i believe. Can you please look into that ,may be that is what you are expecting ?

Hello，

This is exactly our initial problem. In the can boot app, we used the ospi driver from the PDK to set the OSPI to legacy SPI mode. Now, we want to use the ospi driver from the MCAL to set the OSPI driver to legacy mode.

Hello Gary,

what error are you facing ? can you share me the log after shifting the API to MCAL?
