Hi All,
I am trying to navigate around the Picomite Flash file system, but cannot fathom out the required syntax for moving into a directory. I have successfully created a directory called "Test", but cannot make this the current directory.
( The directory is currently empty.)

I have :-
> ?cwd$
A:/
>
> ?MM.INFO(drive)
A:
>
> files
A:/
<DIR> .
<DIR> ..
<DIR> Test
16:06 14-01-2023 4 bootcount
3 directories, 1 file
>

Using CHDIR and assorted combinations of " . / \ $ and Test etc. I endlessly get :-
"Error : Could not find the path"
or
"Error : Expected a string"
or
"Error : Syntax"

e.g.
> chdir "Test"
Error : Could not find the path
or :-
> chdir "A:/Test"
Error : Could not find the path
>

I am running :-
PicoMite MMBasic Version 5.07.06b7
OPTION SYSTEM SPI GP10,GP11,GP12
OPTION SYSTEM I2C GP20,GP21
OPTION AUTORUN ON
OPTION COLOURCODE ON
OPTION CPUSPEED (KHz) 130000
OPTION LCDPANEL ILI9488W, RLANDSCAPE,GP8,GP15,GP9,GP13
OPTION GUI CONTROLS 5
OPTION TOUCH GP16,GP17
GUI CALIBRATE 0, 247, 3863, 1277, -869
OPTION SDCARD GP22, GP5, GP18, GP19
OPTION RTC AUTO ENABLE

on a Waveshare pico-restouch-lcd-3.5 module.

Please-please give me an exact syntax example of what is required !

Also, without an SD card present, some incorrect responses :-
> ?cwd$
A:/
>
> ?MM.INFO$(SDCARD)
Ready
>
> drive "B:"
> ?MM.INFO$(SDCARD)
Not present
> ?cwd$
Error : SD Card not found
>
> drive "A:"
> ?cwd$
A:/
> ?MM.INFO$(SDCARD)
Ready
>

With best regards, Paul.

Nothing so constant as change.

Suggest you update to the release version or one of the 5.07./07 beta before anything else

picomite with latest beta
drive a:
CHDIR only works with directory name in lower case.

Other commands appear to work normally.

Hi TassyJim,
Is that intended, or a bug ?

I've just updated another Picomite from V5.07.06 to v5.07.07b2 :-

I thought that everything was wiped on doing that !!
I still cannot do anything with the added directory.

With best regards, Paul.

My post was to confirm the bug.
On the flash drive, you cannot CHDIR into a folder with any upper case letters in the name.

This is a bug.

The SDcard is OK.

I am not sure when it appeared. All my testing on the new flash system was in lower case.

To use the flash drive, keep your folders in lower case until the problem is resolved.

When updating firmware, the existing file system and flash slots are usually preserved but not always so backups are strongly recommended.

historically, MSDOS and windows do NOT distinguish between upper and lower case in filenames (and by extension, directory names), and i assume this is still the case?

linux (and osX?) do distinguish between upper and lower case, and treat eg "A" and "a" as completely different. i must say this is, on the whole, quite inconvenient!

in MSDOS (ie, pre-1995), file and directory names were forced to uppercase by the operating system itself, and so there was no question over the problem. with the arrival of FAT32 and LFNs, i suspect this strict enforcement started to change a bit. now, the waters are likely somewhat murky with some responsibility pushed on the application program to ensure that it makes no distinction.

someone who uses modern windows may wish to chip in here.

cheers,

The LittleFS file system is case sensitive (like linux). This is documented in the manual. However, I don't understand why CHDIR seems to have a particular problem - I'll look at it - perhaps I'm inadvertently converting the supplied directory name to lower case.

In the meantime just make sure directory names are lower case. Use clean_flash to completely wipe a Pico if required.

Hi Jim, Rob and Peter,
Thanks for your info. I had decided to run the "clean_flash" for a complete wipe, as I currently cannot use the added directory at all!!
Case accuracy for names is not a worry for me - BASIC is generally case insensitive IIRC - but I'll go with what works!
With best regards, Paul.
