I've had success getting the Sigurd Hellesvik Serial Recovery sample to work on an nRF52840 DK with mcumgr cli commands. I'm able to flash the Fanstel 840 with the same bootloader sample with a simple dts overlay file. I have the timeout flags set in the mcuboot.conf file:
CONFIG_BOOT_SERIAL_WAIT_FOR_DFU=y
CONFIG_BOOT_SERIAL_WAIT_FOR_DFU_TIMEOUT=5000
"hello world" is written 5 sec after reboot, so I assume its running correctly. But any mcumgr command times out:
"mcumgr -c acm0 image list"
Error: NMP timeout
The led from CONFIG_MCUBOOT_INDICATION_LED=y only works with the button trigger, not with the wait for DFU. But it doesn't work on the DK either, so I'm not concerned.
I've verified that the mcumgr cli works. As I say, all works fine on an nRF52840 DK.
I used the nRF52840 DK ->All boards base for the project. Maybe I should use another? Don't see anything special for a Fanstel module.
I've only had to move the uart0 pins with an overlay and that works.
I've seen references to these flags, but it fails to build.
CONFIG_MCUMGR=y
CONFIG_MCUMGR_SMP_UART=y
I appreciate any and all suggestions. Thanks.
Bob
