Hello,
I'm having some problems with the SD-cards during boot. Sometimes the system hangs when waiting for the SD-card. When I cycle the power, it might or might not work properly.
I have a feeling that this problem becomes larger when I add more files to the card. This because I tested the SD once and it booted, I then connected the SD to my PC and added some avi:s, a jpeg and two boot scripts in the /etc/init.d/ folder. And after that I could not get it booting again. It hangs when it tries to load the SD. I did the same test again since I was unsure that I had unmounted the SD correctly. Same thing happen.
How do you have the settings for the MMC/SD? I have only "MMC block device driver", "use bounce buffer" and "Atmel SD/MMC Driver" set. Should I change anything? Should I enable "Atmel MCI DMA support (experimental)"?
Thanks!
/Anders |

| Which kernel version are you using? If you have an older variant, upgrade to the latest from www.kernel.org. |
