is there any possibility to erase specific memory ranges within the QSPI flash of our AM263x-CC device using the Uniflash software?

Hi Dominic, No we current do not have support for erasing the specific memory range. I will create a request for this to be added in Uniflash next release.

Furthermore, our attempts to erase specific ranges via the command line have been unsuccessful. We found out that there is a "FlashErase" option, but it appears to perform a full chip erase, which is both time-consuming and unsuitable for our particular u

Can you please tell me if the flash erase that you are trying is for writing a new data at that same location? If yes then this is taken care by our flash write apis that it erases that region first then write the new data.

Hello Nilabh,

we actually need to erase something, and at least not necessarily overwrite it with something new.

Right now we're using a workaround where we're overwriting with a file filled with 0x0 bytes, but the functionality shown in the Uniflash documentation to selectively erase by address range would be a lot more convenient.

Regards,

Dominic
