Hi Daniel,
The LPC313x Linux SD/MMC driver is capable of read/write to SD/MMC/SDIO-Card. I
have assisted several customers that uses LPC313x Linux with SD/MMC/SDIO
read/write without any significant issue.
The upper layer of SD/MMC will request SD/MMC/SDIO read/write through
'lpc313x_mci_request()', which will put the request into tasklet.
After several interrupts (the SD/MMC/SDIO requests are async, handled through
MCI interrupt: 'lpc313x_mci_interrupt()'), the tasklet will call
'lpc313x_mci_request_end()' to return the data to the upper layer.
You might want to join LPC3000 groups for more community support on LPC3xxx.
Regards,
-daniel

Subject: [lpc2000] LPC313x Linux SD-Card driver
Hi
I use the Board from Embedded Artists "LPC3131 Developer's Kit".
I have compiled and installed the apex bootloader and the Linux which is include
as a demo.
NXP wrote some drivers for this board. One of them is the lpc313x_mmc.c driver
which can read from the SD-Card. But the write function isn't
implemented.
Has someone wrote the write function for this driver?
Best thanks, Daniel
