SOFTDEVICE: ASSERTION FAILED at 0x14CBC after fds_record_write SDK 16.0.0 nrf52832 S132 v7.0.1

[nvelozsavino]

I'm getting a softdevice assertion at PC=0x14CBC after calling fds_record_write(NULL,&record), the record contains the following information:

fds_record_t const record =
{
.file_id = 0xF012,
.key = 0x7012,
.data.p_data = p_data,
.data.length_words = (size+3u)>>2u,

};

where p_data ponts to 0x20009cd4 and size = 8 bytes

the record is allocated in 0x2000ef68

The function return success, but before executing the next instruction I get the SOFTDEVICE: ASSERTION FAILED

Before running the code I'm always doing a mass erase on the flash so the record is not found on the filesystem prior to write 

How can I check what's happening?

I'm using the nrf52832 and the SDK 16.0.0 with the softdevice S132 v7.0.1

Hello,

The assert indicates that an internal Softdevice task has overstayed its allocated "timeslot", which could be the flash write task. Could you please double check that the .data.length_words input value does indeed match the size of your p_data buffer? It may seem unlikely, but I can't really think of any other potential reasons for the SD assert to occur right after scheduling the flash write.  

I would also be happy to debug this here if you could share a minimal version of your project.

Best regards,

Vidar
