I´ve use the second batch (september2013) with firmware 0.23. i tried a 8gb panasonic SDHC card, and get a SD card init error after startup. (card is inserted before starting) tests: by pushing the encoder button at startup i get a SD ERROR.
the sd card is formated by win7 with FAT32 and only the uncompressed sd-image is in the root of the SD card filesystem.
could you check the SD card socket pins on the mainboard? I had a few mainboards where they were loose and i had to resolder them. SD-Error means it can't communicate at all to the card.
After spending further 8euro for a small 2gb trancend sd card, i'm able to load files from sdcard. But the thematic isnt solved ! It gives a SD card standard and its important to get the normal/full compatibility with the lxr board. Please check the crc cmd55 sources.
yeah-i will look into this matter. what kind of card do you have exactly.It would really help If I had a card that does not work. All cards I have work flawlessly.:-/
@fcd72 yes. I have to migrate it to GitHub one day for version control. @dubtoms plenty! A pattern is about 50kb if I remember right. A kit is even smaller.
I'm still working on the 0.24. The 'revert value to original after step-automation assignment' bug is tougher than I thought I hope to finish it over the weekend.
Just finished and had trouble using this Transcend 16GB SDHC card. Switched it with an 8 gb Sandisk card out of my ESX and all is well. Makes more sense that way anyhow. Just wanted to give everyone a heads up.

I can confirm this. I had also trouble using this card. A 2 GB SanDisk works fine now.

any idea ?
I have a 8GB kingston and samsung SDHC and both are working fine.
is in the sd-card file.zip the 0.21 firmware.bin included ?
or must this swapped to the 0.23 firmware inside ?

my last build from first batch, had the same issue - but there i tried a old 256M card and 512m card,
my friend use yet a 2gb sd card,
So i assert its a software issue from the LXR.
my SD card is like new and works in all other devices fine.
have the sd card file included 0.21 firmware ?
i have tried to swap this with 0.23 but same result.
i have spoken with embedded developer and found this:
http://stackoverflow.com/questions/955587/initialization-of-a-microsd-card-using-an-spi-interface
in my point of view its important to have a wide range of supported SD-cards,
in few years you are unable to buy (small) SD-cards.
But the thematic isnt solved !

I also included it in the GitHub repo for better version control
