File system error code -49. What does it mean?

Well, it is our board with a XCC3100-JR device and not the TI EVB.

Operating voltage is 1.8V. Serial flash is MX25U8035, and it looks like it supports all the required commands.

Hi,

You are working on a pre-regulated 1.8 mode. Actually, it is 1.85V so please refer to the online DataSheet to make sure you meet the specification.

Another thought, have you formatted the serial flash for the 1st time. You need to do it before you can save anything on it. The format is possible using Uniflash tool.

Thanks for the suggestions!

I correct myself on the 1.8V information, the radio and flash are operating at 1.85 V.

The function sl_FsDel(..) returned with the error code -49 as well, so there seems to be no way to programatically format the serial flash from the host.

There is absolutely no possibility to use Uniflash with our boards.

Hi,

sl_FsDel() API is not the way to format a SFLASH. Actually, from host you do not have the capability to format the SFLASH. Only Uniflash has this option.

Can you try to format the SFLASH using Uniflash? If you need guidelines, let me know.
