External SPI flash programming during production

[Jeff]

I would like to program an external flash using SPI during production and I was wondering if there is a tool available already or if Nordic can put this feature into nRFgo Studio. I have used other solutions where this type of tool is provided. I need to program and verify up to 2MB so it needs to be fast. I can load a temp program to take data from UART and write to SPI but UART is only 1Mb. The other way is to set SPI pins to input and hook up an external flash programmer. Can someone recommend the best way to do this flash programming? Thanks.

Hi Jeff,

I don't think we have any tool of option to program the external SPI flash from Nordic. You are pretty much on your own in this case. You already proposed 2 options that I think is feasible. I'm not sure which one is better but I'm more into the latter, where you use an external programmer to program the SPI flash. I'm sure the production programmer can handle the task.

Could you try to contact Elnec or Hilo regarding their programmer ?
