Module sdif_18xx_43xx.h, line 266, has comment that max MMC bus width is 4. Is that true? I need to get 8-bit MMC transfers going. Can I update driver?

Question asked by Rick Rigby on May 6, 2017

I'm trying to get the LPC43xx SD/MMC example to open my MMC card. No success yet. I need help on how to see the bus responses to the commands being sent. Also, we want to run my MMC device using 8-bit data width. Line 266 of sdif_18xx_43xx.h has a comment that more than 4 bit witdh is not supported. How do I add it? (How do I get info on the CIU register details?)
