Zynq-7000 SoC will not boot from NAND. Read/write data from u-boot is correct.

描述

My system will not boot from NAND.

I can access NAND correctly when booting from a different source and I can verify the data is correct.

REBOOT_STATUS returns the following:

0x200D - The BootROM is unable to find a valid header within the search range.

解决方案

Ensure that there is a pull-up on the NAND BUSY signal.

The internal pull-up in Zynq is disabled in the BootROM (refer to TRM table 6-11).

This pull-up is enabled in the FSBL (or ps7_init.tcl) and that is why u-boot works correctly.
