uSD failure

I'm getting the following error at startup:

• CONGRATULATIONS & WELCOME TO THE IMSAI 8080esp
• You can disregard any earlier NVS_NOT_FOUND error for now.
• • you will configure the NVS later, refer to the Configuration guide.
• Seeing this message suggests that you've soldered the PSRAM (SPI SRAM)
• successfully and it is passing its tests, see above.
• Check the uSD tests below to know if that has also been soldered
• successfully.
• (If this is not a new IMSAI 8080esp then the PWR switch is faulty.)

Is there an SD card image somewhere that I can download and reload?

[mbenson1]

I soldered on the last of the switches, and loaded both firmware and image 1.11.0. I checked for continuity from the ESP32 to the uSD socket, and checked for bridged pins. The only thing I can't do is check for broken or bent internal contacts. I looked under a stereoscopic microscope as best I could. The contacts appear to be ok. Below is the error I get now:

Do I need to completely desolder and replace the SD socket?

[mbenson1]

I found and fixed the problem. My resistor network was faulty. I replaced it with a new one, and now I have blinky lights!
