hi, all
when i read the SarbreAI souce about SD card, i have a question for iomux setting of USDHC.
for example, the SD_CD pin connects with GPIO_1 pad in SabreAI.
According to chip manual , the pad should be set to ALT6
but in source, it set the GPIO_1 pad to ALT5
like this:
//SD1_CD
MX6Q_PAD_GPIO_1__GPIO_1_1,
i don't know what the difference between them is.
B&R
Hi fang
for CD,WP one can use these dedicated pins and
any GPIOs. Idea is well described in
Chapter 15 Adding Support for the i.MX53 eSDHC
MX53UG MX53SUG.book
Best regards
chip
