Hi Team,
NCS v2.3.0
nrf52840
my project works as expected with CONFIG_APP_MSC_STORAGE_RAM=y
but I need storage FLASH_FATFS
Hi,
Could you please show the error that you get?
Best regards,
Dejan
windows error looks the same as in devzone.nordicsemi.com/.../nrf52833dk_nrf52833-usb-mass-storage-issue
Hi,
I have made an internal inquiry. I will get back to you when I get more information.
Best regards,
Dejan
Hi,
The issue might not be with any of the samples (mass and chat) independently, but with the way how they are used together. We have looked into it, and it might potentially be configuration/devicetree/partition problem.
Could you provide information on how this issue is connected with your other issue?
You could also have a look at this discussion for some further hints.
Did you have any progress related to this issue yourself? Could you provide status update from your side?
Best regards,
Dejan
Hi,
so far nothing has helped.

Hi,
This may or may not be related to your issue, but due to some blocking behavior when working with USB, all shell_print statements in model_handler.c should ideally be either removed or replaced by either printk or LOG.
Regarding the persistent USB storage, I have tested successfully with a following configuration changes applied to your project:
prj.conf
CONFIG_NVS=n CONFIG_SETTINGS=n CONFIG_PM_SINGLE_IMAGE=n # CONFIG_PM_PARTITION_SIZE_SETTINGS_STORAGE=0x8000 CONFIG_SOC_FLASH_NRF_PARTIAL_ERASE=n CONFIG_BT_SETTINGS=n CONFIG_APP_MSC_STORAGE_FLASH_FATFS=y #CONFIG_APP_MSC_STORAGE_RAM=y
storage_partition: partition@0 {
label = "storage";
#reg = <0x00000000 DT_SIZE_K(8000)>;
reg = <0x00000000 0x00020000>;
};Thank you Dejan, I will be satisfied with this option if I can replace shell_print to some kind of uart_tx?
To give out an msg array to the uart.

In version with FOTA and CONFIG_PM_EXTERNAL_FLASH_MCUBOOT_SECONDARY=y
when I add to prj.conf your changes
when I set CONFIG_NVS=n I have error

There might be a problem with coexistence of storage partition with external flash partition. It would be useful if I could reproduce this issue. Could you make a minimal sample which I could use for this purpose?
Best regards,
Dejan
Hi,
sure

Hi,
I have tested your sample and found 2 pairs of conflicting lines in your prj.conf.
CONFIG_NVS=y and CONFIG_NVS=n as well as CONFIG_PM_SINGLE_IMAGE=y and CONFIG_PM_SINGLE_IMAGE=n
CONFIG_NVS=n CONFIG_PM_SINGLE_IMAGE=n
fixed it but the error is still the same
