Dear Team TI,

I know to create new file on external flash but is it any option to append data on existing file?

Thanks & Regards,

Hi Mubin,

Append operation is not supported by CC31xx/CC32xx device filesystem. If you want to append data, you need read all previous content of file and write them back with appended data.

But be aware that SPI flash have limited number of write cycles (100k/write cycles per sector) and from this reason is not suable for logging purpose.
