Bootloader(DFU) for 51422

[Elliot.Chao]

Hi,

I try to modify 51822 device_firmware_updates code for 51422. But I have a problem.

When I run my code, my cell phone can connect to 51422. I can click DFU button in master control panel UI and select a file to download. But the progress always 0% and it will disconnect after few seconds.

When I stop debug mode, I think that have generated a exception and I don't know why.

Do you have ant suggestion for this issue?

Do you have device_firmware_updates source code for 51422 that I can got?

Thank you.

I use 51422 with S310 Stack

I found that if I call the ble_flash_block_write() to write flash, that will occur exception Is ble_flash.c problems?

Hi Elliot

I made some modifications to the bootloader in the SDK to have it run on the S310.

Please find the modified example, as well as a DOC showing the changes I made, attached.
