Hi,

I am using the SPWF04 and want to update the filesystem via UART.

Is it possible?

For the SPWF01 there is the command AT+S.HTTPDFSWRITE but thats not working with the SPWF04.

I've read in another post that it might be possible with FLASHER/ST-LINK (wired UART/SWD) but I can't find any further informations.

Thanks for your help!

In the SPWF04 the filesystem is stored in the STM32's internal flash, hence you can use the STM32 Flash loader demonstrator (go to

and search for FLASHER-STM32 or STM32 Flash loader demonstrator).

The starting address of the filesystem is:

- 0x8100000 for Application Disk

- 0x8110000 for User Disk
