How to program the QSPI flash memory on Hi-Res 2 DAC/HPA boa

[DWHW]

(1) Is there any tool for programming the QSPI flash memory on the Hi-Res 2 DAC/HPA board?  

(2) Is the QSPI flash memory on the board empty?

(3) I assume that the firmware resides in the XHRA-2HPA-TQ64-C chip and it allows programming the QSPI flash memory through a PC software. Is my understanding correct?

• (1) Is there any tool for programming the QSPI flash memory on the Hi-Res 2 DAC/HPA board? 

If you can access the QSPI lines, you can use any thirdy party programmer that supports the programming guidelines provided in the XHRA-2HPA-TQ64 datasheet (Flash section).

But Hi-Res 2 DAC/HPA QSPI flash is programmed by XMOS and you don't need to program it.

• (2) Is the QSPI flash memory on the board empty?

No, it is factory programmed by XMOS with the XHRA-2HPA firmware binary.

• (3) I assume that the firmware resides in the XHRA-2HPA-TQ64-C chip and it allows programming the QSPI flash memory through a PC software. Is my understanding correct?

No, the XHRA-2HPA-TQ64 (fixed audio chip) doesn't provide support to program the external QSPI flash.

 

Hope it helps!

Thanks for the answer.

So, if I want to customize this design reference board, I will need to:
 
1) Request the firmware binary from XMOS by emailing to XMOS
 
2) Use a third-party SPI flash programmer, program both the firmware and the custom flash configuration into a QSPI flash IC
 
3) Replace the QSPI flash IC on the board with the newly programmed one
 
Right?
