Hello,
I have been having issues trying to flash my AST-CAN485 board with a byte mismatch. I believe it’s an issue with my bootloader. I am using the ATMEL ICE Programmer, and have verified my connections as per the AST-CAN485 documentation.
ASTCAN-485 ATMEL ICE
VCC 4
GND 2
RST 6
CLK 1
FTDI UART0 TX 3
FTDI UART0 RX 9
VCC External Power Supply
GND External Power Supply
My current issue is that I am getting a mismatch sync message, as a result of my system clock not being a strong enough signal.
As a result my Atmel Studio 7 can only register a 5v reading, but cannot get the board ID.
Has anyone come across this issue previously?
Thanks,
V
