Ticket #10071 (closed defect: fixed)
external SD cards not working on XO-1.5
|Reported by:||sascha_silbe||Owned by:||wmb@…|

|Deployments affected:||Blocked By:|
I'm having trouble using any of my two SD cards in an XO-1.5 (CL1B / D4). While the cards are detected fine and listing the root directory seems to work, trying to access a subdirectory or running the self-test yields one the following errors:
SDHCI: Error: ISR = 8000 ESR = 10 Data Timeout SDHCI: Error: ISR = 8002 ESR = 10 Data Timeout
Happens with OFW Q3A33 / EC 1.9.21 and OFW Q3A35 / EC 1.9.24. SD cards: Silicon Power SDHC Class 6 16GB, takeMS SDHC Class 6 4GB.
The 16GB cards was used for running Debian on an XO-1, so it's known to work fine. The only issue on XO-1 was that it often required two boot attempts ("SD card failed to power up" or something like that).
