Feedback on The Back Shed_ V4.7 _ MX170 SDCard FAT32 Driver
Test Harness for CFunction FAT32 FileSystem driver (c) Peter Carnegie 2015 Ver 1.6

Has anyone had problems with above?

The issue I've had is the SD Card (FAT32) died when this program began wtiting to it.
It isn't just a problem with the File System, both Format and Fdisk respond with "Insert Disk" and go no further.
Linux doesn't see see card at all.
Have been using this card for data logging with a Mictomite Plus LCD Backpack for about 6 months without problem,
but now want to use the MM+ for another project.
The idea is to adapt this program (V4.7 _ MX170 SDCard FAT32 Driver) to continue the logging on a cheaper Mictomite 2.
The first step was to run this program unmodified, and that's as far as I have got.
Has anyone else had problems?
Before I try another SD card I'd like to know what I have done wrong.
Do different brands of SD card behave differently?

Hardware:-
PIC32MX170F256B-50I/SP (28 pin) (purchased from Silicon Chip)
Catalex MicroSD Card Adapter v1.0 11/01/2013 catalex.taobao.com (purchased from Silicon Chip)
SD Card - Samsung MicroSD-HC Class C2 8GB
Connected together on breadboard as per comments in program.
(Vcc = 3.3V,pins 13,28. Gnd,pins 8,19,27. Core reg. cap. 10uF ceramic // 47uF Tant pin 20)

Firmware/Software:-
MM2 Micromite_V5.04.08.hex

Hello.

Welcome aboard.

Peter Carnegie is no longer an active developer of MM code, so using any of his older routines could be a problem for you, as there is zero support available for those routines now, and no source to look at.

Your best bet might be to use the SD card driver that matherp wrote as a replacement. It is not as fancy, but it does the job if you desperately need SD card ability on the 170 series MM chips. See this link as a starting point.

Thanks for the advice. I'll have a look at that or perhaps a serial EEPROM.

Geoff wrote a lovely little Cfunction for talking to 11AA160 or 11AA161 one-wire EEPROM chips. They are very cheap(about 30c each!), and have up to 1,000,000 write cycles. Have a look at this thread.

They currently are my go-to EEPROM device even over and above the standard I2C ones.

EDIT: If you DO decide to play with these devices, make sure you use the latest Cfunction from page three of that thread. The first one had a couple of bugs that Geoff squished during that thread.Edited by Grogster 2018-02-16

Also the latest working version is included in the Micromite firmware zip file.

phil99 said Linux doesn't see see card at all.

Not even in system logs (e.g. via dmesg)?

Even with a corrupted file system it should be seen there (assuming a working SD slot and if needed SD to uSD adapter).

Take a look here http://www.thebackshed.com/forum/forum_posts.asp?TID=8492&KW=data+logger&PN=1&TPN=1

I've just bought 5 8MB ones for one and a half UK pounds! I used a couple to upgrade ESP01's and I've just finished mounting another on a 8 pin dil socket so I can have a play with a MM.

Thanks for the tip. dmesg showed nothing so I put a good card in the reader which created /dev/sdf, ran dmesg again to see what changed, then again after replacing it with the damaged card. this is what came out:-
Output from dmesg: "sdf: detected capacity change from 1015808000 to 0"
Then ran GParted: "Error opening /dev/sdf: No medium found"
fdisk /dev/sdf returned nothing at all.
Since all the program did was write some data, I imagine it has done so in the wrong place - over data needed by the OS. Unless someone knows how to restore that the uSD card is as good as dead.

That's a dead card, not one where the OS structures were overwritten.

(In that latter case, dmesg would show the card and fdisk etc would show its size and other info. You would then be able to reformat/partition it.)

My goodness, what a blast from the past ! Brought back some memories :)

Should I update this driver or has time passed this by?

Take care
