fs_erase couldn't erase flash on S140

[Alice]

Hi,

I'm using nRF5_SDK_13.0.0_04a0bfd on nRF52840.Basing on the ble_app_multilink_central example, I want to write some data to flash to save. So I use the fstorage. After calling the fs_init function, I erase the page which I want to write data to, but it wouldn't generate the FS_EVT_ERASE event. So the code would stop here and wouldn't run at all. fs_erase returns 0 and I have register the system event in the ble_stack_init function

static void sys_evt_dispatch(uint32_t sys_evt){
fs_sys_event_handler(sys_evt);
on_sys_evt(sys_evt);}

The fstorage setting as the attachment. Could you help me have a look? Thanks.

Hi, I could not see any obvious mistakes in the code snippet you provided. I tested integrating this example into the ble_app_multilink_central example, and it seems to run correctly. Could you try the attached main.c file to see if it works for you?

ble_multilink_central_main.c

Best regards,

Jørgen

Hi,

Have you tried to set the flag variable as volatile? Another thing you could try is to not sleep in the while loop..

Hi Jørgen， I just copy the fstorage_test function in your code to my application and call the fstorage_test function before, it's ok and the data can write to the flash. To my strange, what I do in my code is the same as your code. But I still couldn't write data to flash. I found that the fs_config.p_start_addr is 0xFB000, while mine is fs_config.p_start_addr = (uint32_t *)0xFC000; How does FS_REGISTER_CFG configure the address? It's global variable in my code while it's local variable in your test code.

Hi emdi, thanks. I have tried to set the flag variable as volatile, but I still couldn't write data to flash.

Could you try to not sleep but rather have a busy wait loop (remove power_manage() call) ?
