<p>The correct spelling of the program is <em>openFPGALoader</em> with FPGA and the “L” of “Loader” in uppercase.

<p>Gowin’s FPGA may fails to be detected if <strong>JTAGSEL_N</strong> (pin 08 for <em>GW1N-4K</em>) is used as a GPIO.
|

To recover you have to pull down this pin (before power up) to recover JTAG interface (<em>UG292 - JTAGSELL_N section</em>).</p>

<p>Some firmware version cannot be flashed on Linux-based systems. Version 2024122312 is such an example. It seems this version was not published on the <a class="reference external" href="https://api.dl.sipeed.com/TANG/Debugger/onboard/BL616/">SiPeed website</a>, however some boards sold have this firmware.</p>
|
||
<p>The cause of the problem is the debugger on the Tang Nano, specifically the firmware of this debugger. This firmware can be easily updated by following <a class="reference external" href="https://wiki.sipeed.com/hardware/en/tang/common-doc/update_debugger.html">these</a> steps.</p>

<p>This is a device issue, erase its Embedded Flash using Official GoWin Programmer (preferentially in Windows) and SRAM too, then you can use openFPGALoader again.</p>
