I like to confirm i have all the correct parts before moving on with troubleshooting my WeeCee.
I've attached the picture of the parts lists i downloaded from PCBWay - i only added a few comments, where needed.
So use CS4237B-KQ instead of CS4237B-JQ. Do not use 24LC04BT/SN EEPROM... I'm having a problem with it and it says on flash that it has insufficient memory (4kB is probably not enough). Before that 24LC16B/SN was used. What do you want to help with at WeeCee?
Ok, so I checked the sound chip - it is a CS4237B-KQ, so that's fine, I guess the list is incorrect and I didn't even noticed it. I used 24LC16B/SN for EEPROM, not 24LC04BT/SN.
The biggest problem that I have at the moment is that my WeeCee doesn't detect any microSD cards. Adjusting the boot options in the BIOS to "boot from SD card" doesn't seem to work. I'm guessing I didn't solder it properly, but I already tried to reflow solder on it twice. Maybe I didn't properly solder the pins of the SOM304 module?
1) Do you have SOM304RD52VINE1 ?
2) What power supply are you using to power the board ? (poor quality power supply can cause this)
3) The SD CARD may be well powered but the fault will be elsewhere. Recheck the U4 component, cold solder joint after soldering is the problem..
If you take a picture of the board and post it here we can check it.
