Hi All, I'm trying to create a hybrid program using the USB CDC ACM example as well as the flash_fstorage example from SDK16. I've been able to get the USB CDC ACM example to work on the dongle, however I'm having issues getting the fstorage to work. Because I'm not using a soft device, i've been trying to use the mvcm backend. I get an NRF_SUCCESS when I do rc = nrf_fstorage_init(&fstorage, p_fs_api, NULL); However, when it gets to here: print_flash_info(&fstorage); My output looks like: ========| flash info |======== erase unit: 536871936 bytes program unit: 2457 bytes Which both of those seems wrong... for NRF52 I believe erase should be 4096, and program should be 4... Any ideas what could be happening? Thanks!

Strange Program Unit Value with fstorage

Hi All,

I'm trying to create a hybrid program using the USB CDC ACM example as well as the flash_fstorage example from SDK16. I've been able to get the USB CDC ACM example to work on the dongle, however I'm having issues getting the fstorage to work. Because I'm not using a soft device, i've been trying to use the mvcm backend.

I get an NRF_SUCCESS when I do

Fullscreen

1
rc = nrf_fstorage_init(&fstorage, p_fs_api, NULL);
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

rc = nrf_fstorage_init(&fstorage, p_fs_api, NULL);

However, when it gets to here:

Fullscreen

1
print_flash_info(&fstorage);
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

print_flash_info(&fstorage);

My output looks like:

========| flash info |========
erase unit: 536871936 bytes
program unit: 2457 bytes

Which both of those seems wrong... for NRF52 I believe erase should be 4096, and program should be 4... Any ideas what could be happening? Thanks!
