Raspberry Pi Forums

Hi All,

New to the forums, intermediate Linux understanding - purchased a couple Pi's (one destined to be running Raspbmc, and the other Wheezy web server)

SD cards: Patriot LX 16GB microSDHC's (PSF16GMCSDHC10) with adapter
Distros tried: Raspbian-wheezy-2012-08-16, Raspbian-R3 (unofficial), Raspbmc (latest).
Issue 1: Both OS's are having the same problem, they start booting and run into mmc0 never released inhibit bit(s) followed by dev mmcblk0 errors. "Warning: drivers/mmc/host/sdhci.c:1048 sdhci_send_command+0xb58/0xc34()" and numerous timeouts.

Verified the "LOCK" tab is in the correct position to permit writing to the card

Attempted fixes:

1) rpi-update kernel - since can't boot Raspbian to desktop I downloaded rpi-update and attempted to run manually from terminal using "ROOT_PATH=/media/rootID BOOT_PATH=/media/bootID rpi-update" also tried rpi-update 128/192 options with no avail.
(each time using HardFP's)

**Side issue - raspbian configures boot partition with 0 space remaining making it a hassle to update manually offline or edit config.txt file??** Is there a fix for this?

2) cmdline.txt - adding sdhci-bcm2708.enable_llm=1 sdhci-bcm2708.sync_after_dma=0 (individually or together)

I've spent a solid day on this and unable to find a workaround. Day two already well underway, at this point I'll try anything (except another type of card)!

Thanks in advance!

The debian wheezy you can download creates a small boot partition approx 50-75MB in size.
There is free space on it to alter stuff.
In the beginning there were sd card issues, but those should be resolved with the current downloads.
Have you checked the voltage between TP1 / TP2? It should be at least 4.85V for stable operation.
If that looks fine, I really would start suspecting the sd cards. If you test with another known brand sd card, you can rule that out as possible cause of your problems. Digital camera's, mp3 players, gsm's...Plenty of sources to find a sd card...
