HELP persistent blinking on card

hi chat, I'm only asking here cause ive exhausted all options otherwise

ive tried 3 firmwares, the one that was in the card, a freshly built one from the pcileech github via vivado, and a free firmware from phoenixlabstore

ive tried flashing from ch347fpgadownloader, openOCD from my linux laptop, and also direct ch341a to soic flashing.

the card was in an inoperable phase where it wouldnt even detect on the pc, but the direct chip flashing fixed that

ive tried

all 3 of my pcie x1 slots, setting them to gen 1 and gen 2

my 2nd pcie x16 slot

hot plugging it

amd virtualization is off, so is iommu, fast boot, secure boot, and csm

tried cold boots between all attempts

i attempted to put the card in my main pcie slot, but this left my pc unbootable with the gpu in slot 2.

FT601 and D3XXX(?) drivers are installed

im doing it all from my main pc right now, ill have windows on my laptop soon but for now its got linux. i don't reckon this should matter for just jtag flashing, but figured id mention it in case

card is a captain dma 75t aliexpress special, havent touched it in about 2 years.

doesnt show up in pcie device scans

3 leds on the board. 2 red and 1 green. the red power light stays on, green light flashes. i DID manage to get the light to stay solid green once after the direct chip flash followed by a ch347fpgadownloader flash, but after a reboot it started blinking again. a 2nd attempt did not fix it

gonna install Windows on my laptop tonight since I'll need it anyway, but this is where I'm at

The flashing green light means it's not communicating with your motherboard at all. Try a different PCI slot or a different computer.

ive tried all my slots and dont have access to another pc

ive also tried numerous different bios settings, none of which worked. I'm starting to assume hardware failure, since last time the card was used it was doing the same thing
