AVR Freaks

Hi all,

I am trying and failing to program the SAMA5D2 MPU on the SAMA5D2 Xplained Ultra board with the bare-metal "getting_started" example (provided in the SAMA5D2 Software Package). I have the following setup:

• SAMA5D2 Xplained Ultra (Rev. B) Board (powered via a Micro-USB cable connected to J23)
• Atmel-ICE (connected to my PC and with its 10-pin IDC cable connected from its SAM port to J11 on the board)
• FTDI TTL-232R-3V3 Cable (connected from my PC to J1 on the board)

I have successfully built the "getting_started" code using GNU Make with the command 

make TARGET="sama5d2-xplained"

to produce the binary "getting-started_sama5d2-xplained_sram.bin", but I now don't know how to program this into the SAMA5D2 on the board.

I have tried using SAM-BA (first disabling EDBG and external boot by shorting JP1 and JP9 on the board to see "RomBOOT" appear on the terminal after reset) but I cannot connect to the board via J-Link. I have tried the command:

sam-ba -p j-link -b sama5d2-xplained -a bootconfig -c readcfg:bscr

This gives the error:

Error: No J-Link devices found

However, I can connect to the board using a serial link with:

sam-ba -p serial -b sama5d2-xplained -a bootconfig -c readcfg:bscr

This gives the output:

Opening serial port 'COM6'
Connection opened.
Executing command 'readcfg:bscr'
BSCR=0x00000000 / BUREG0
Connection closed.

For my purposes, I need to be able to program the device using JTAG, so continuing further with a serial link is not an option. I have also tried building the same code using IAR (thinking it might be easier to use their Embedded Workbench to program the binary) but the code size exceeds the link-limit for the evaluation version!

If anyone can help me do the following I would be very grateful:

1. Connect to the SAMA5D2 on the board using JTAG;
2. Program the "getting_started" binary into the SAMA5D2;
3. Debug the binary.

Thank you in advance,

Ed King
