Latest AtoMMC sources.

[Prime]

Hi all,

After some enquireies at the last ABUG about obtaining AtoMMC boards, I reached ot to SirMorris and got his permission to produce a bunch for people**. So having re-spun the board I want to put the latest firmware version on it.

Currently I'm using 2.9.3, is there any more recent than this, if so where can I get it?

One problem I have run accross, is that if I program just the bootloader to the PIC, no mater what card I put in I can't get it to bootload, green LED just comes on and stays on and hangs.....I've tried a couple of different cards formatted as FAT, and then firmware dropped on card (as I know the bootloader relies on the firmware being on contiguous sectors). But nothing

I do know that the boards work as if I get a PIC from a working AtoMMC, read it on my device programmer and write it back to another PIC, it all works as it should. I can boot of the card load the Atom software collection etc.

Anyone have any clues?

Cheers.

Phill.

** Note I have no intention of going into wholescale manufacture of these, but will be publishing my work on github, and had 10 board sets made,
which I will be happy to build and distribute to people at ABUG meetings, certainly to the couple of people that initially enquired.

Do you mean the 4KB AtoMMC ROM?

The latest is version is 3.0.2, available from here:
https://github.com/hoglet67/AtoMMC2/rel ... tommc_3_02

There are both PIC and AVR builds.

Or do you mean the PIC Firmware?

One problem I have run accross, is that if I program just the bootloader to the PIC, no mater what card I put in I can't get it to bootload, green LED just comes on and stays on and hangs.....I've tried a couple of different cards formatted as FAT, and then firmware dropped on card (as I know the bootloader relies on the firmware being on contiguous sectors). But nothing

As far as I remember, you need a really small card (<1GB) formatted with FAT16.

I use an ancient 128MB card.

Also, it will only program the firmware if it's different from what's already programmed.

I've tried a 1GB SD card and a 32 MB MMC card, both formatted as FAT16, both fail

Also, it will only program the firmware if it's different from what's already programmed.

Shouldn't be an issue here, as I've just programmed the bootloader to the pic with my TL866II-Plus.
Oddly I can't get my PicKit3 to program it (on a little breadboard), keeps complaining of over-current

Cheers.

Try a 128MB partition:
