Onboard external flash - USB - PC transfer question

[xxb9075]

Hi guys,

So here is our application:

we have an external 1GB NAND flash on the board with a nRF52840 SoC. We save sensor inputs to the 1GB flash and when we connect the USB, we hope to dump the data on the 1GB flash as a csv file to the host PC.

Would you give suggestions on how we should utilize this? Note here we have the flash driver already in place, we are not so familiar with the USB implementation here.

Any advice or example is really appreciated!

Thanks,

Richard
