Hello, I'm debugging some issues with mmc_spi. I have 3 mini-SD cards: - transcend 2G - works - Sandisk 2GB ultra - works if we play games with the CPHA bit, but then the transcend card breaks. - ATP Pro - does not get very far: mmc1: error -38 whilst initialising SD card Thinking it might be a problem with the PXA270 SPI driver/hardware, I switched to using the gpio_spi driver, and got exactly the same results. I have verified the power is stable. Next, I plan to dig into the driver and protocol, but wondered how its working for others: - has 2.6.31 mmc_spi has been tested with a number of flash cards and works? - I noticed the driver is playing games with the SPI mode to keep CS high during some clock pulses. Is there any concern that the CS will glitch while changing modes? - any suggestions as to what to look for?
