iMX6ULL evaluation board NAND support

awong121 — Tue, 01 Sep 2020 01:27:23 GMT

In the imX6ULL evaluation board schematic on the page for Flash there is a MTFC8GACAAAM on the lower left. It is not connected to anything as far as I can see. Am I right? I think it is just a footprint. Why is it there? I want to solder a BGA NAND flash to the board but this footprint seems to be not connected electrically to anything. i want to see whether I have missed anything. Thanks.

It's for TSOP-48 NAND. http://nxp.com/doc/imx6ullevkhug

Hello,

MTFC8GACAAAM is eMMC. According to section 2.6 (eMMC)of i.MX 6ULL EVK Board Hardware User's Guide:
The eMMC interface is connected to USDHC2 of i.MX 6ULL. It can support up to eMMC 4.5, the
eMMC device is not populated by default on the EVK board. To boot from eMMC, remove the Micro SD
socket and populate the eMMC device, and then change the boot device switch (SW601) settings
(OFF, ON, ON, OFF) as shown in Table 3 Additionally, the BOOT_CFG settings must be adjusted for
the specified eMMC device by exchanging the pull up/down resistors.

NAND on the EVK is mentioned as MT29F32G08CBADBW. Use section 2.8 (NAND flash) of the Guide
for more details.
