Hi. I recently assembled a Minimig 1.97ITX. Unfortunately, after programming the ARM, uploading the minimig1.bin files, and the Kickstart image, the machine won't start.
I can access the OSD menu, select files, and change the configuration, but after a reset, there's no response—a black screen. Without the ADF file selected, the Kickstart screen doesn't appear.
The LEDs are behaving strangely: after powering on, the DISK led flashes, reads for a moment, then goes out along with the POWER led, only showing +5V. I double-checked the soldering; there are no bridges, cold solder joints, nothing. I tried a different microSD card—no effect.
Could this behavior be caused by, for example, a counterfeit Xilinx? I bought it on Aliexpress, but from a seller where a friend of mine also bought them—they all work fine after soldering. Does anyone have any ideas?

Well, it turns out that at my age, you can't trust your own eyes anymore. Only after using a microscope did I see that I had a jumper on two pins of one RAM chip. I fixed it, and everything worked fine.
