Using the QuadSPI Flash on i.MX7 SABRE SDB

daweichen — Sun, 11 Sep 2016 19:41:05 GMT

The NXP i.MX7 SABRE SDB has a on QSPI flash memory. The schematic shows a MX25L51245GZ2I-10G device is populated. The schematic also indicates moving/removing some resistors.

In addition to the resistor changes and SW2 Boot Config setting, are there instructions for programming and erasing the on-board QuadSPI flash memory device?

At minimum, I would like to download a U-Boot image to the flash memory, so I can at least boot the SABRE SDB and load a Linux OS over a Ethernet network.

Thank you very much,

Dawei
