Error to upload multizone.hex on the Arty Board

HiFive Unleashed
1

Hello,

I’m trying to remake the demo of Multizone Secure Iot Stack for a school project.
So I followed the tutorial but I’m stuck when loading the .hex file on the Arty A7 100T card.
There are some errors related to JTAG : “JTAG scan chain interrogation failed: all ones”.

I have checked and rechecked the wire connection between the Arty board and the ARM-USB-TINY-H but everything is correct.

The definition of the file “/etc/udev/rules.d/99-openocd.rules” is correct too.

I ask if anyone can help me, I’m starting with openOCD. thanks.

This is the error output :

This doesn’t have anything to do with the HiFive Unleashed. And doesn’t appear to have anything to do with SiFive either. I would suggest filing an issue in the hexfive/multizone-secure-iot-stack github tree asking for help.

thanks for your reply !

Aldwin,
per our reply to the issue you filed at https://github.com/hex-five/multizone-sdk/issues/49:

“Your hardware (100T) is not compatible with Hex Five’s X300 bitstream. The X300 bitstream requires the Xilinx Arty FPGA 35T.”
