Issue with STM32Flash utility #3

Closed Mani-Sadhasivam closed 5 years ago

Mani-Sadhasivam commented 5 years ago

Hello,

Flashing the pre built firmware available in the repo using STM32Flash utility fails to start the application. Below is the output of the utility:

sudo ./stm32flash -b 115200 -w RAK5205_LF_trackerboard.bin -v -g 0x08000000 -e 255 /dev/ttyUSB0
stm32flash 0.5

Looks like the entire firmware is not getting written into Flash memory (note 64%). However, flashing the Zephyr binary works fine.

Are you sure that you want the 433MHz version? It seems that most people would want the HF version (868MHz or 915MHz) of the firmware, but you might be the exception.

@afremont I just took that binary as an example. But I can't flash either HF/LF version firmware.

afremont commented 5 years ago

Are you using an ST-Link V2 device? If so, maybe upgrading the firmware in the device will help. I haven't received my tracker board yet, so I have no experience with flashing it yet. It should be delivered today. :)

I ran into the same problem. When I used the STM32 Flash loader demonstrator it worked fine though so it may be an issue with the stm32flash utility. STM32 Flash loader demonstrator is Windows only though. I noticed this firmware project is a bit too dependent on a windows environment, which is unfortunate. I do hope RAK will continue to improve and work on a more multiplatform approach in the future.

This issue is resolved after dropping the -e flag.
