mattairtech / BOSSA

BOSSA is a flash programming utility for Atmel's SAM family of flash-based ARM microcontrollers. The motivation behind BOSSA is to create a simple, easy-to-use, open source utility to replace Atmel's SAM-BA software. BOSSA is an acronym for Basic Open Source SAM-BA Application to reflect that goal.

Hangs/stuck when flashing ATSAMD21E15B #4

Open tinkerBOY-git opened 4 years ago

tinkerBOY-git commented 4 years ago

Bootloader works fine on ATSAMD21E15B but I cannot get BOSSA 1.7.0-mattairtech-3 to upload a binary file. It hangs/stuck on when it's time to "write".

@tinkerBOY-git did you ever find a fix for this?

/* If ARDUINO_EXTENDED_CAPABILITIES is defined and set to 1, 3 additional commands

//For SAMC21E16
#define ARDUINO_EXTENDED_CAPABILITIES   0

I was able to get the write to work by turning off extended capabilities in the board_definitions_x.h file which disables multipage fast write mode. I'm guessing the reduced RAM doesn't allow for this write mode? Everything works after building the bootloader with this option off only it take s~80sec vs ~5sec to upload the FW and it seem to not want to verify unless I separate out the command.
