Vajra on Arty A7-100: Artix-7 FPGA Development Board

Hardware

Platform Shakti: Shakti is an open-source initiative by the RISE group at IIT-Madras, which is not only building open source, production grade processors, but also associated components like interconnect fabrics, verification tools, storage controllers, peripheral IPs and SOC tools.

Microcontroller	C-CLASS
Frequency	50MHz
Flash	0B
RAM	128MB
Vendor	Xilinx

Configuration

Please use vajra ID for board option in “platformio.ini” (Project Configuration File):

[env:vajra]
platform = shakti
board = vajra

You can override default Vajra on Arty A7-100: Artix-7 FPGA Development Board settings per build environment using board_*** option, where *** is a JSON object path from board manifest vajra.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:vajra]
platform = shakti
board = vajra

; change microcontroller
board_build.mcu = C-Class

; change MCU frequency
board_build.f_cpu = 50000000L

Uploading

Vajra on Arty A7-100: Artix-7 FPGA Development Board supports the following uploading protocols:

• ftdi

• ftdi

• jlink

• jlink

Default protocol is ftdi

You can change upload protocol using upload_protocol option:

[env:vajra]
platform = shakti
board = vajra

upload_protocol = ftdi

Debugging

Debugging - “1-click” solution for debugging with a zero configuration.

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

Vajra on Arty A7-100: Artix-7 FPGA Development Board has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
