Hello,

I have some issue with SD Card on OVMS 3.1 I don't know how to fix the "bug"

I can't write or read file on SD Card, but I can make directory :

OVMS# vfs ls /sd

[DIR] 05-Nov-2018 20:46 logs/

13.5k 23-Nov-2018 19:45 Vectrix_bak.dbc

14.0k 11-Nov-2018 22:04 Vectrix.dbc

13 01-Jan-1980 00:00 FOO.TXT

13.5k 23-Nov-2018 19:45 vx1.dbc

OVMS# vfs mkdir /sd/testdir

VFS directory created

OVMS# vfs ls /sd

[DIR] 05-Nov-2018 20:46 logs/

13.5k 23-Nov-2018 19:45 Vectrix_bak.dbc

14.0k 11-Nov-2018 22:04 Vectrix.dbc

[DIR] 05-Dec-2018 21:14 testdir/

13.5k 23-Nov-2018 19:45 vx1.dbc

OVMS# config backup /sd/cfg.zip

Creating config backup '/sd/cfg.zip'...

Error: zip failed: No such file or directory

OVMS# vfs rmdir /sd/testdir

VFS directory removed

And If I try do load dbc file it's crash

OVMS# dbc load test /sd/vx1.dbc

I Have try my SD Card on a PC is working, I have try example code "sd_card_example_main.c" from SDK "esp-idf\examples\storage\sd_card\main", It's working to, no crash.

My guest, is the hardware is OK, esp-idf is OK, but they is something in OVMS main code make this bug.

I have delete both esp-idf, and OVMS folder and clone again, compiled again, but it's the same issue.

Thank you for your help.
