I want to know whether every card working well ? BecauseI'm workingquoted
For 83xx MMC-over-SPI support, the presented concretemethods I usedquoted
as you do, but only 256M card seems good, 512M or 1G/2Gcard all havequoted
some problems=20 So far I don't have cards larger than 256M. Will try to get one=20 though. =20Thanks, if you have any new test report pls contact me.=20 Just tested with Apacer 1GB MicroSD (connected through dumb=20 adapter), it works quite well here. I've successfully wrote=20 10 mb file onto ext2 formatted partition...
Oh, thanks for your info. The card I used is Kingston 1G SD card.

BTW, a fews days ago Joakim Tjernlund made a heavy fix for=20 spi_mpc83xx.c to resolve clock glitch. But it looks no any=20impact for=20quoted
me, but maybe it has positive effect for you.=20 Yup, I use it. =20 Btw, which mmc driver are you using? The one from MPC8610HPCD=20 BSP or mainline's mmc_spi?
:-( the mmc driver now in the MPC8610HPCD BSP is ported from uClinux by me, it has many problems, because at that time MMC-over-SPI driver doen't exist in the kernel.
