Programming Module getting stuck/stalls when trying to debug

Hi,

This solution worked. I looked on the website for the module and it looked like they came with a boot loader and soft device already loaded. I erased the chip using nrfconnect and it works fine now.

Thank you

Yes, the Softdevice is loaded along with the app FW. But maybe you have a bootloader present as Turbo suggested. Some modules come pre-programmed with one. I suggest that you do a full chip erase and try again.

Thanks for the reply. I was under the impression that a soft device was also uploaded when you downloaded or debugged with Segger embedded studio. Do you know if this is correct? I am not sure about the bootloader but is there a way to check if there is a bootloader on the device?

Thanks

No softdevice / wrong softdevice? Bootloader present?

In the "bootloader present" case, the application won't be started - the bootloader has a CRC for the application, which will not mach the new program.
