Alternative to use sd_flash_page_erase using FDS

[Arepa]

Hi there,

On my project I was working using sd_flash_xxx functions to write the whole flash pages or erase it, so I added peer manager to my project and I had to switch my functions from sd_flash_xxx to FDS, because I was getting hangs on my code when using sd_flash.

Are there a sd_flash_page_erase equivalent using FDS?

How can I select the address to write or erase using FDS functions?

and What is the max number of pages I can use? can I use 40 pages? I was using 40 writing/erasing about 40 flash pages using sd_flash_xxx functions.

Thanks

Arepa

If you don't plan to pass any context pointer to the handler, you can use NULL. I attached here a quick example I used the fstorage_simple in to SDK v13.0 ble_app_hrs example. You can test: main.c

Hi Hung, Thanks for the example, it works fine also I read the fstorage_simple and port it to ble_app_hrs, and it work fine. But when I tried to port it to my project for some reason it is not working and not triggering any event. for my main project I am using GCC

You may want to check in your application what cause the problem. i would suggest to comment out some of the functionality, one by one, such as stop advertising for example. Until you have the flash working as in the ble_app_hrs. 

Note that the event for radio notification is the same as the flash event, so you should be careful if you use radio notification.

Hi Hung, I solved my problem. I was calling the fs_xxx functions before enabling some SD functions I had to re-order the way how I call some SD functions and I was erasing/storing data where my application was allocated also I fixed it and now my application is working so far so good. thanks for the suggestions
