What are the minimum and maximum values for the lengths that are arguments to the flash_write or flash_read functions?

And can you please tell me how to create block_number and page_number using offset in function Flash_offsetToBlkPage?

Also, is there any explanation about the FLASH API?

thank you

Hi sygo,

flash_write

Maximum 256 Bytes i.e. the Page Size per QSPI transfer. Handled by API directly for multiple transfers.

flash_read

Should be < Flash Total Size. 8MB in memory map mode.

Everything is abstracted based on the sysconfig details. Link to the document - https://software-dl.ti.com/mcu-plus-sdk/esd/AM263X/latest/exports/docs/api_guide_am263x/CUSTOM_FLASH_SUPPORT_GUIDE.html

In the Flash_offsetToBlkPage function, if an offset is entered, the block number and page number are converted and returned. I am curious how to create the block number and page number using the offset.

And Flash_eraseBlk erases in blocks. What is the maximum and minimum number of blocks?

Hi sygo,

Please refer to the Flash Datasheet. These details are independent of controller functioning.
