Thanks Bjorn, Using the files you provided I found that I was linking pstorage.c instead of pstorage_raw.c which is why everything was not working. The single bank works for me now.

You should not have to doanything else than switching from dfu_dual_bank.c to dfu_single_bank.c. I have attached a copy of SDK v9.0 where I have converted the S110 Dual Bank Bootloader to Single Bank to my answer.

Hi Bjorn, I switched to SDK v9.0 S110 v8.0 and dfu_single_bank.c and still have trouble getting single bank to work. In dfu_init() the pstorage_register(&storage_module_param,&m_storage_handle_app) call returns error 7, which is block_size or block_count error. The problem is I can't find anywhere that the block size is set for storage_module_param. Do I have to set that? Another error from dfu_prepare_func_app_erase() if my image size is 71492 bytes then the block_size needs to be 2 because image size could change later and image_size somehow has to always be divisible by block_size, since block_size is defined in the bootloader? Does DFU somehow pad the image size so it will be a multiple of block_size? Thanks.

Thanks, I will try that and update once I have made the change.

Instead of using the example on GitHub, which is based on SKD v6 and has not been maintained for some time, I recommend using SDK v9.0 and S110 v8.0.

You can convert the S110 Dual Bank Bootloader to a Single Bank Bootloader by replacing only one file, dfu_dual_bank.c with dfu_single_bank.c.

Are you using a revision 2 chip?
