Program flash memory without Xilinx platform cable

Question

I am using a picozed board with the Zynq 7015 processor. I can currently generate either a *.mcs or *.bin image and boot either from the QSPI memory or a SD card. In the field, I would prefer not to have any platform cable connected. The SD card option would be interesting, but since the board will be moving at high speed, I am afraid it is not a viable option. My question is: is it possible to write to the flash memory without being connected with the platform cable? Like sending the file through serial port (preferred option), or reading it from the SD card (removed after)? By the way, the application uses the standalone OS.

Melanie,

Yes, you can definitely read/write QSPI from a standalone software program. U-boot, for example, has commands to do just that. There are a variety of means available for obtaining the data, which could be via ethernet, SD card or serial (not sure if that last one is standard off the top of my head, but reading from serial is not difficult - there are plenty of standalone examples). Or you can just look at how U-boot does the programming and incorporate the open source into your own program (with the appropriate GNU disclaimers).
