Hi All,
I'm using NRF52832 for our product. I test bootloader functionalities with development kit. The software system is also tested separately by directly programming to the device.
But the device will never connect after I flash the bootloader "examples/dfu/bootloader_secure_ble" from the sdk13. Even can not recover with "nrfjprog -f nrf52 --recover", it always shows the following message:
The following is the schematics:
Is the bootloader brick the chip? What could be the problem?
To be short:
1. erase/flash softdevice and any program is ok;
2. whenever flash the bootloader then the device can no longer detect by jlink;
Thanks,
