I'm using fds and dfu at the same time with SDK15.3

but it seems that there are some ram conflict or something wrong

I have read some issues in devzone

but i didnt get a solution

please give me some suggestion

thanks

Hi,

Error 11 corresponds to FDS_ERR_NO_PAGES, which means that fds_init cannot install the FDS file system because there is not enough room in the Flash. Have you tried erasing the entire flash using 'nrfjprog -e' command before running the example? Is your application taking up all the space in the flash?

Best regards,
Jørgen

Is 'nrfjprog -e' command same as Erase all in nrfconnect programmer?

and it seems that there is much space remain in flash

by the way i set FDS_VIRTUAL_PAGES 3

                          FDS_VIRTUAL_PAGE_SIZE 1024

                          FDS_VIRTUAL_PAGES_RESERVED 0

actually i just want to save device name and some settings that user can set in app

may not exceed 100byte

HI

this is the origin code i got

0420.zip

and i put it to a clean ble_app_template in SDK15.3

it may loss someting to include

after i fix it,i got it compile as below

6685.ble_app_template.rar

and i'm using nrf52832 on my custom board

Thank you

Hi,

I do not see error 11 in the second project, but I do see error 3 (FDS_ERR_UNALIGNED_ADDR) from call to fds_record_write() in kls_fds_write(). You need to align the data that you pass to this function. Since wait_for_fds_ready() is called regardless of the error returned from fds_record_write(), the application will get stuck here when no write has been scheduled.

You can solve the error by adding align-attribute to the array definitions:

uint8_t __attribute__((aligned(4))) default_pwd[9] = { 0xAA,0xA2,0x05,0x48,0x59,0x50,0x52,0x4f }; //HYPRO
uint8_t __attribute__((aligned(4))) default_record_interval[5] = { 0xBB,0XB1,0x01,0x14,0x00 }; //20
uint8_t __attribute__((aligned(4))) default_device_name[7] = { 0xCC,0xC3,0x04,0x47,0x54,0x30,0x36 };//GT06

Best regards,
Jørgen

I just try to use my nrf52dk and it worked.......

and if i use my own custom board it failed

but why?

[Aku]

I just fix the problem in a MYSTERIOS way

just moved the fds initial up

AND IT WORKS

WHY????

i'm so confused, is this a bug?

since another IDE has no problem on the original code , and the original code can work on nrf52dk

by the way i'm using SEGGER Embedded Studio for ARM

and i use internal rtc

I'm not sure which issue you fixed, I tested both ways in the project you uploaded and they both seem to work fine here.
