Hi,
I've been using the nRF5 SDK (17.1.0) USB Mass storage code for a data logger I have made. I am using a memory chip larger than 16KB and that code has bugs when you go over that size. So I'm moving to the nRF Connect SDK on advice I read on different forums. My first question is, has anyone used this code on a NOR Flash that is 2Gbit in size? Will it work?
So, I've used the nRF5 SDK for many years and have recently moved over to the nRF Connect SDK. It's a bit of a learning curve, but it's making sense. I am missing something, though, when I try to build and run the Mass sample. I am using the nRF52840dk which has a QSPI NOR flash attached. Instead of using the adafruit board like in the example, I'd just like to get this running on the nRF52840dk (PCA10056).
I have copied the Mass folder into a different location where I keep all my examples (and DevAcademy files), so it's out of tree of the SDK.
I opened the existing application. I created a new build based on the nRF52840dk_nrf52840. In the build file I optimized for debugging so I could see what was going on.
Then I typed the following into the nRF Terminal:
west build -b nrf52840dk/nrf52840 -- -DCONFIG_APP_MSC_STORAGE_FLASH_FATFS=y
I left out the location of the files since I was in that directory (and the first time I tried it there was an error that it couldn't find the files). I also changed the board to the nRF52480dk.
Everything build and compiles correctly and I can flash it on to my board. However, when I then plug it into a windows machine, It says I need to format the device in order to use it. Ok, that seems normal, but when I try to format it, I says the size is unknown and the sector size is unknown and the format fails.
Here is the output of the build after typing in the above command:
PS C:\Nordic\ExampleProjects\mass> west build -b nrf52840dk/nrf52840 -- -DCONFIG_APP_MSC_STORAGE_FLASH_FATFS=y

It looks like the memory chip is found and everything is okay. I am worried that it says NAND, but I looked up the adafeather board in the example and it also seems to NOR not NAND.
When I plug the board into my computer, I don't see any more messages on the COM or RTT.
Thank you for you help,
ian
