Hi,
I have run into an issue with nrf52840 on pca10056 v1.0.0 board. The softdevice is SD v6.1.0. It seems to be a hardfault which cause a reset when I tried to call sd_flash_write(), sd_flash_page_erase() is OK though. The address and buffer is 4 byte aligned, the number of word is 1024.
Following the parameter of the callback error that Softdevice invoked
if SD is not enable, there will be no problems at all. Strange things is the very same code run without issue on nrf52832 S132 v6.1.0.
I am appreciated if anyone could provide a hint why SD assert at that pc location.
Thanks in advance
new found, if I seperate the whole page write (1024 words) into 2 x 512 words, it does seems to work. This is a workable walk-around, but I am still interested on why S140 v6.1.0 assert, it should be able to handle up to a page write according to the specs. hmmm. Did I miss something !!!
I see this on my side as well. The assert indicate that the SoftDevice spends too much time writing to flash. I am not sure why though, as the API documentation states that the maximum number of words is 1024 (number of words in one flash page). I will look more into it and hopefully have more info on Monday.
Thanks, I am glad that you could reproduce it. Was thinking it is my code doing incorrectly. Please take your time, I divide it into 2 writes ( half page each) as walkaround, seems to be OK for now.

That sounds good. I have created an internal bug report so that it can be fixed in a future SoftDevice release.
Just saw the 6.1.1 release, any chances that this is fixed. Thanks
