openFPGALoader VS RV-Debugger-BL702

Another way to flash the devices in Linux is to use https://github.com/trabucayre/openFPGALoader which supports a variety of cables and devices. It also supports the Xilinx Virtual Cable protocol, which allows you to use Xilinx tools like ChipScope with almost any cable.

Even though I saw multiple proposed solutions around the web, I could not get the Gowin cable to be detected under Ubuntu Linux as well, so neither the programmer nor GAO could work. I tried opensource openFPGALoader as an alternative to the programmer (but not GAO of course..), but got some issues as well (not with cable, but with certain bitstreams causing the programming to hang). So the easiest solution for me to stick with Windows version.

i could/should eventually open a ticket on the openFPGAloader indeed

Most Linux users seem to prefer openFPGALoader, but if you need GAO and the other suggestions don't work you might have to use a Windows VM, thankfully Gowin IDE supports (supported?) Windows XP/7 if you want a lightweight guest.

You might be able to use a tool like openFPGALoader to load a bitstream onto your board from macOS.

Try openFPGALoader. It works fine in Windows 10 and Linux for me. https://github.com/trabucayre/openFPGALoader

There's the open source openFPGALoader with explicit support for macOS if i remember correctly, I'm not sure if it supports all the features but it should be a good starting point.

u/PCB4lyfe all you need are just the drivers for the USB blaster. To load the bitstream you can use openFPGALoader https://github.com/trabucayre/openFPGALoader

OP, if that doesn't work, and you feel comfortable installing openFPGALoader (https://github.com/trabucayre/openFPGALoader), I can send you the GPIO demo bitstream to put on your board.

The humble BL702 is an external 144MHz and 132KB of RV32IC that has at least 8 bits shared between CPUs and some cross-interrupt lines. This is so they can basically implement a [url=https://github.com/sipeed/RV-Debugger-BL702] a sub-$4 serial console + a JTAG port on the same serial cable] (at China's cost to China, that's cheaper than an FTDI-2323-this-quarter part. This is the same CPU with different peripherals attached (notably trades Zigbee for Wifi) as the BL602

This question is in reference to the wiki article here: https://www.reddit.com/r/GowinFPGA/wiki/tutorials/gowin_analyzer_oscilloscope/ As well as the project here: https://github.com/sipeed/RV-Debugger-BL702

talking about the RV-debug "dongle", that has it's own FW too https://github.com/sipeed/RV-Debugger-BL702 and i'm wondering if there could be different version or my own is not up-to-date. how could i check the current running version?

It's an interesting irony that even the way to do inexpensive JTAG now is via RISC-V. It's slower than a Segger, but I can afford to leave one cabled up to all the things.
