How do I access the SD card formatting in the Axoloti software?

#1

Hello all,

I've found a few topics mentioning that I need to go to Window -> Remote. I don't understand this; the only options I have are Axoloti, Keyboard and file manager. I understand from previous posts that this option is somehow hard to find/hidden, but I can't seem to get to the bottom of it! Sorry for density if it's obvious! :wink:

OK I found this post from Jonhannes explaining the workaround with the current version of the software:

Sorry, the 'remote' is removed in 1.0.11 since it was not up-to-date anymore.
As a workaround, to format an sdcard with axoloti:

create an empty patch
add a "script/script2" object, and click the edit button on the script object
put this in the script:
void setup(){
FRESULT err = f_mkfs(0, 0, 0);
if (err == FR_OK) LogTextMessage("format done");
else report_fatfs_error(err,"");
}
void loop(){}
click the "live" button
After several seconds, "format done" appears in the main window.
I will add an object to the factory object library to format cards.

You can also use the util/format object, no need to make a new object.

Great, thanks for the info.

The util/format module seems to have stopped working with the new firmware for me - it just fails straight away. It says no SD card in the main window too. Any ideas?

Thanks.

Ive just tested util/format here on latest firmware/axo 1.0.12, and works ok.

if the card is not showing as mounted, thats probably the cause.

perhaps the card is faulty?

I would try to test the card with a card reader on your computer, if its ok then format it there (fat) and try again...
in addition, try another card in axo.

Thanks. Good to know it's still working for you. It's a cheapo card, so I did think it might be that but I wanted to rule out firmware first.

It actually doesn't show up at all - in the main Axo window so I presume it's not mounted. I'll try a card reader. I'm beginning to think I should buy a new one from a non-shitty brand.

I've been having similar problems with formatting my SDcard. I've tried mentioned above methods but none of them worked.
Whenever I try to use any sdcard related operation I keep getting on the console:

file error: FR_DISK_ERR, filename:"/"

Whenever I try util/format object it goes directly to failed.
After (FAT) formatting

Is it the SD card I'm working with? It's strange because it's not working on 2 different I have.

Thank you

I found this topic as I experienced a similar issue - Suddenly the Axoloti was unable to read any files (FR_DISK_ERR).
But the card would work perfectly fine on my computer. I suspected that the reader of my unit was broken.
Then I tried this util/format object and it worked. Luckily there was nothing of importance on the card. It's still weird.

A possibly related issue (or cause) is, the "Board -> Enter Card Reader Mode" had stopped working a while ago (my OS is Ubuntu 16.04).
It would freeze while mounting and I would pull the USB plug from the Axoloti.
Afterwards I would run "fsck" on the card and it reports "Dirty bit is set", which I then unset.
