Part Number:AM3352
Hello,
We have an issue during a WARM reset. The board should boot from NAND, but it tries to boot from a Wifi peripheral that s connected to the MMC1 interface.
The MMC0 interface is connected to a SDcard connector and only used in production for initial programming of the on board nand flash.
Our sysboot (4:0) is set to 00100. This means UART0/XIP/MMC0/NAND.
So, in production it boots from MMC0 (SD card), and in the field it boots from NAND.
But once the Wifi slave (connected to MMC1) gets initialized, we have a issue at the next warm reset.
Since it is connected to MMC1, I would not expect any interference in the boot scheme. "00100" never addresses MMC1 as a boot device.
How can we block the attempt to boot from MMC1 ?
