Tool/software: Linux
Hello,
I am seeking some guidance on designing a system using eMMC with the DM3730. In the TRM for the DM3730, on page 3572 (Section 26.4.7.6), it states:
The ROM code supports MMC/SD cards, with some limitations:
• Supports MMC/SD cards compliant with the Multimedia Card System Specification v4.2 from the MMCA Technical Committee and the SD I/O Card Specification v 2 .0 from the SD Association. Includes high-capacity (size >2GB) cards: HC-SD and HC MMC
• 3-V power supply, 3-V I/O and 1.8-V I/O voltages on port 1
• Supports eMMC/eSD (1.8-V I/O voltage and 3.0-V Core voltage) on port 2. The external transceiver mode on port 2 is not supported.
Does this mean that eMMC MUST be connected to port 2? Or is this simply noting the voltage differences between using the two ports.
Brief background: We are currently using an SD card connected to SD1 as a fail safe backup boot from the PoP NAND on the DM3730 SOM from LogicPD, and are looking to swap the SD card out with eMMC.
