New SD/MMC Host driver, problem
Hello
Im making my very first Linux driver at the moment, it's a Host driver to a custom made SD/MMC card controller for opencores.org. I wonder if someone has experience in writing those kind of host drivers, or blockdrivers in general? Because i encounter some problems that i hope some one can give some advice on. Without no debug tool except printk the debugging is tedious. 1) After the card initialization process,i got the following printout from the system: Code:
mmc: new SD card at address 0002 able to track to the bus.c, but were does the "mmcblk0 : " line comes from? |
