CONFIG_APP_MSC_STORAGE_RAM VS FLASH_FATFS

[Sergnrf]

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

I set CONFIG_APP_MSC_STORAGE_FLASH_FATFS=y
and the disk does not open in Windows, it gives an error window when connecting nrf USB.

Thank you.

Hi,

I have replicated your issue using NCS v2.3.0. There are currently 2 options how you can fix the build error. 

First option:

//in prj.conf, comment out configuration option CONFIG_BOOTLOADER_MCUBOOT
#CONFIG_BOOTLOADER_MCUBOOT=y

Second option:

//in prj.conf, make a following change to CONFIG_NVS
CONFIG_NVS=y

With either one of above-mentioned changes, you should be able to build your project successfully.

Best regards,
Dejan

Hi,
#CONFIG_BOOTLOADER_MCUBOOT=y
mass storage works, but FOTA update stopped working.
When can we expect a complete solution to the problem?

Best regards,

Hi,

Could you please describe how you perform FOTA and provide all steps to reproduce your issue?

Could you provide your new project if there are differences with previously uploaded one?

Could you also provide log which would show us the error that you get when performing FOTA?

Due to vacations and potential limited staff availability, I cannot provide the expectation for problem resolution. However, I will look into your problem together with our developers and I will keep you updated with relevant new information. I have already reached out to our developers internally.

Thank you for your patience and understanding.

Best regards,
Dejan

Hi,

There were no differences from the previous one, I added your recommendations, the mass storage worked, I don’t get rtt errors, the update most often does not start and freezes, or ends with the message connection time out.

Best regards,

We might need all necessary steps for reproducing your problem.

What happens when update freezes? Does it make any progress and then freezes?
Could you please show message connection time out?

can fill the slot1 once, but writes Confirmed: FALSE, Active: FALSE, Permanent:FALSE

still looks like CONFIG_PM_EXTERNAL_FLASH_MCUBOOT_SECONDARY=y it doesn't work 

large files does not react at all does not update in any way.

I apologize for the delay due to work switched to 2.4.0 NCS we hope to replace the FOTA to Mesh DFU

Hi,

Due to vacation time and hence reduced staffing, we would need more time to look into your issue. This issue has been reported, but some delay in replying should be expected. I will get back to you when I get new information.

I am sorry for any inconvenience.

Thank you for your patience and understanding.
