fs: file write error (-5)

[andy]

Hi~:

I use microsd card on nrf21540, the sd card mounted success and write file success, but after some time ,I found write error.

And this issue can be reappeared. Can you give me some suggession.Thanks!

I use the ncs V1.9.

Hi,

Are you using a nRF21540 DK, or a custom board with this chip? I assume that the SD card is connected to the nRF52840 and not nRF21540?

How is the SD card connected to the chip? 

Can you post your prj.conf and overlay files?

Can you check if setting the log level of the SDMMC library to DBG reveals more details about the failure?

Best regards,
Jørgen

Is the SD card mounted in an external SD card socket? If so, what kind of socket? Is the socket soldered to the board, or connected through jumper wires/breadboard?

Do the error occur at a specific file/point in application, or at a specific time, or does it happen at random?

Have you tested if the latest nRF Connect SDK v2.1.0 release have the same issue?

Hi Jorgen,

I am facing the same issue in NCS 1.9

I am able read and write data on SD card successfully.

the issue is that when i am trying to download the  data to sd card and  its work upto 5 to 6 % of total data. after that I am getting error in fs_open function .and the error is -5;

The total size of data is 2MB.

The same code work properly in NCS 1.5.0.so every thing in term of hardware and SPI connection.

Hi,Jorgen.

Is there any progress,I can be sure that the IO port is fine, but can not guarantee the quality of the wiring.

I want know is there any successful case?

I update ncs to V2.1.1,  this issue remains.The sd card is mounted OK,and can write some data to sd card, but  fs_sync costs about 10 seconds and return -5.

I tried running your sample, but the main.c file is using some decoding that my system can't understand, or it is somehow broken. Can you re-upload the sample you used for testing in nRF Connect SDK v2.1.1? I can then try to reproduce it on my end.

O, sorry, the main.c is encrypted.Please try again.4454.sample.zip
