nimbus.cpp dfu-util: Last page at 0x900606b3 is not writeable

Hi, I’ve been fiddling with my daisy field and I’m running into a strange problem.

I had nimbus built and working on my field a couple weeks ago. I’ve since been spending lots of time working on new code. I never intentionally made any changes to the nimbus code or the daisysp library, but have been uploading lots of different code to the daisy. today I went to re-upload nimbus (hoping to play around and take notes on the great interface it uses), and I got this fail message:

dfu-util: Last page at 0x900606b3 is not writeable

It builds fine, but but can’t program to dfu, exiting with that error code 2

After reading a bit, I double checked to see the Makefile still says
APP_TYPE=BOOT_SRAM
I guess I can just re-download daisyExamples and see if that helps, but would like to know what the underlying cause could be. Any ideas?
Thanks

Hi @mbb,
It might be worth re-flashing the Daisy Bootloader. Let me know if that helps.
And there are threads with similar error (like this one (resolved) Error when using program-dfu with Diasy bootloader and the APP_TYPE = SRAM ) that might be worth checking out.

I will give that a try, thanks!
