nRF24LU1+ Bootloader in nRFGo Studio

[Simon Third]

Hi All,

I've just been trying to program some of my USB dongles, nRF24LU1P-F16, via nRFGo Studio. They are recognised fine, and seem to be operational after programming, BUT....I get "Circuit was not programmed correctly" in the log messages box. Verification does not report positive results either.

I've checked the 16k Flash option but it still gives the same results.

Any Ideas?

Thanks Simon

Hi Simon,

1. Which version of nRFgo Studio are you using?
2. Does this verification error happen every time?
3. Have you tried using a different hex file to verify that the one you have is not going into the bootloaders address area?

Hi Hakon,

I'm using 1.16.1.3119 Studio.

I think I've found the issue. Turns out the chips I was using where 32k parts, and selecting the 16k check box option caused the problem.

Would you expect the same error to occur when I use the 16k parts when the program is bigger than 14k? I'm at 14002 bytes currently so getting close to overwriting the bootloader.

Also, can you get the Studio Log window to be cleared at the start of each programming cycle? It would make it clearer when programming many devices.
