[Raspberry Pi] SD card timeouts #841

Closed PascalBoeschoten closed 12 years ago

PascalBoeschoten commented 12 years ago

I'm using a Raspberry Pi with devel-20120614193607-r11315 on a 16 GB Kingston Class 4 SD card.

OpenELEC regularly locks up for 10 seconds. Usually this occurs while navigating and sometimes during playback. I tailed the message log and saw that these errors occured every time it locked up:

Jun 21 17:28:01 openelec user.err kernel: [ 1350.909342] mmc0: final write to SD card still running Jun 21 17:28:11 openelec user.err kernel: [ 1360.887503] mmc0: Timeout waiting for hardware interrupt - cmd12. Jun 21 17:28:11 openelec user.err kernel: [ 1360.887696] mmcblk0: error -110 sending stop command, original cmd response 0x900, card status 0x900

Full log: http://sprunge.us/UCgM

It runs perfectly smooth otherwise, though!

Increasing init_emmc_clock from 50000000 to 80000000 in the config.txt seems to significantly reduce this issue, it now only rarely happens.

can you please report this together with your exact sdcard specs/modell/data in this thread: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=63&t=5057 please note there too we use bootc's latest 3.2 kernel. you can also put in the link from this issue report there for any needed discussion

Updating to devel-20120621213209-r11380 containing the newer kernel solved it. I thought I was already running the latest build, because according to the wiki this contains the latest builds: http://sources.openelec.tv/tmp/image/openelec-rpi/, but it looks like I was wrong.
