Hi~~!!
My processor is DM3730CBP.
I use SDIO/MMC2(8bits) for eMMC, and SDIO/MMC1(4bits) for SD-Card.
May I ask
What is the maximum length of these SDIO/MMC trace?
Is it need impedance matching?
Is it need equal length of these trace?
Why pull high resistor need to close to device not processor?
Thanks!!!
