Update:

Tried set different `bcm2835gpio_speed_coeffs`, not work.

Tried with `interface sysfsgpio` other than `bcm2835gpio`

This makes openocd works on programming nRF52832 with the RPI3B, meanwhile it will slow down the programming speed much.

But at least, it worked in the end.

Thx for the clue.

Noticed someone there posted that he make it work on RPI2 other than RPI3B.

So, I tested different version of RasPi with the same TF card.

Result:

Quite weird for me. But at least, I can make it work on RPI2B for now.

I'll try it on Pi Zero later.

Seems this issue is caused by the difference between RPI2 and RPI3 .

I guess there should be someway to make it work on RPI3. Help needed on this.

Someone in this thread suggested that the error message is because of bad connection: https://www.scooterhacking.org/forum/viewtopic.php?t=45

Can you try to do an eraseall first trough nrfjprog on a computer where you have JLink installed?

We don't officially support OpenOCD but there are several users here on the forum that uses it, so maybe someone has any ideas.

You can also try to ask in the OpenOCD forum
