Hi David,
I've tested this with SDK 16.0.0. I didn't make any modifications to the bootloader except for changing the public key. To test it, unzip the attached zip and program the softdevice and bootlaoder in \dfu_test\bl+sd. Then try to do DFU with the included app_dfu.zip package.
Note: there seems to be a bug in the latest pre-release of nrfutil. Please make sure you're using nrfutil v.5.2.0. https://devzone.nordicsemi.com/f/nordic-q-a/54202/error-of-invalid_object-when-using-nrf-connect-desktop-after-generating-dfu-zip-file-with-new-keys
Hi Vidar,
Do you have the document for bootloader?
How it initializes and sends data package to from the APPs to bootloader?
I mean the shakehand of the communication between the Apps & bootloader.
Thanks,
David
Hi David,
So does it work now when you append the new line to the text string?
Hi Vidar,
Sometimes, most of the time it sends 185 bytes and it does not stop. It’s only working about 10%.
Even though, I only send 14 bytes with new line at once but it keeps sending 185 without stopping. The data is random.
Regards,
David
Hi Vidar,
See belowm frame#3274 has 18 bytes, which main CPU sends over to BLE CPU. The BLE CPU automatically random data (185 bytes) which starts from frame#3320 and never stop.
Regards,
David
Hi David,
Please upload your project with instructions on how to reproduce if that is possible. I don't have enough information now to determine why random data is sent in a loop.
Hi Vidar,
This issue was from my STM32 main CPU. I notice it keeps sending message to nordic CPU. So I just fix it from my MAIN CPU & it works ok now. Other corrupt register of the Nordic CPU issue, which I will post other thread.
Thanks
