burning bootloader and uploading program

RE: burning bootloader and uploading program

Arduino doesn't use a programmer, but a serial/usb bootloader (not sure what). This can be used to update the application running on the device. However, if you try to upload a bootloader, perhaps this bootloader doesn't want to replace itself. You have to ask Arduino about details regarding this.

So now we are trying to do this directly with a programmer. Is the breakout board powered correctly? What is the voltage on your VDD? Does your JLink programmer support that voltage? It is a known issue that some evaluation boards use a low voltage, and that not all jlink programmers support this voltage.

Can you show me a picture of your JLink setup, and verify that your board is powered externally (not via the programmer)?

Best regards,

Hello Edvin,

I am able to burn bootloader and upload Blink sketch to the Adafruit Feather nRF52832 breakout board. I am able to accomplish this using Arduino v1.8.13 IDE through the USB port. Please see the following:

devzone.nordicsemi.com/.../USB.pdf

When I try with the Jlink using a 10 pin connector, I get the following error:

devzone.nordicsemi.com/.../JLink.pdf

When I run nrfjprog I get an error asking to run log.log.

Attached is log.log

Please advise on what I can provide to aid in the diagnosis.

I remain unable to

Hello Craig,

[quote user="Edvin Holmseth"][/quote]

I am using Bootloader "0.3.0 SoftDevice s132 6.1.1.

What is this?

Is this at all related to the nRF5 SDK? Or are you using the Arduino IDE?

What is bootloader version 0.3.0? Where did you find this?

If you have a JLink programmer, can you please try to download and install nrf command line tools, and use the command:

nrfjprog --program bootloader.hex --verify

What does it say then?

Hi Edvin,

The Adafruit Feather Is a breakout board for the nRF52832 which is very useful for prototyping.

http://www.adafruit.com/product/3406

I have my own project using the Adafruit module.

http://www.adafruit.com/product/4077

My problem is, I can't seem to burn boot loaders or upload programs.

The error I get for all devices including the Nordic nRF52832-DK is "Timed out waiting for acknowledgement from device. Failed to upgrade target. No data received on serial port."

I have check all connections to the nRF52832s which seem to be OK. I am trying to gain insight on what causes the above stated error and how to overcome it.

I appreciate your help.

I have never seen an Adafruit Feather before, and I don't know how they work, just so that we are on the same page here. Does this have an on board debugger? Or how would you usually program it?

I am still not sure if this is a question on "How do I implement my own custom bootloader?" or "How do I program my adafruit feather?".

Hi Edvin,

I get it. Things are far from normal anywhere on the globe. In answer to your question, I have tried the following methods you have described. I ave used nrf52832-dk, JLink programmer, and USB. Have not tried serial or BLE. Last night I did have success burning to an Adafruit Feather nrf52832 using JLink to first run msddisable then burn Bootloader followed by USB uploading program. Unfortunately, I can also use this method to upload to the nrf52832-DK. Hope this gives you some insight. I know I must be close but I just can't seem to uncover the missing link. Stay well,

Where do you get this error, and how do you try to upload your program? Do you use a debugger? Or BLE? Or Serial (nrfutil) or USB(nrfutil)?

NB: We are really short staffed due to Summer Holidays in Norway. You must expect some extra delay in technical questions these days, I am afraid. I am sorry for the inconvenience.
