LPC4337 SD/MMC problem: Can't read EXT_CSD register. Other non-data commands are working (CMD0, CMD1, CMD2, CMD3,,,CMD7). After I fixed a CLKDIV bug so I could run the acquire process at 400kHz things started to work. I cannot read the EXT_CSD though. I'm getting a data timeout. How can I try it without using DMA? (or how can I get DMA to work?)

Hi Rick,
As mentioned in the support case you have solved this, maybe you can share your working project so other can benefit from it.
Thanks in advance!
