I build my own BlueSCSI's to save money and have built about 30 version 1.1 boards. I am now replacing my v1.1 boards with v2 boards. I ordered 15 PCB's partially built from JLCPCB. I did not order the LVT245, LVT125 0.1uf caps and U3. Everything else including the small resistors were placed on the PCB.
I've built five so far. Four are not initiating. The four not working have the activity light comes on the BlueSCSI with one long blink for 5 seconds then off, then long single blink for 5 seconds. I have reflowed the boards and touched up all the pins and pads, cleaned and recleaned the boards. I have continuity.
The logs all state the same thing except the working one, it adds this to the end of the log.
Clock set to: 203MHz
Initialization complete!
Disabling status LED
INFO: Pico Voltage: 3.192V.
My question is what is the IC that I need to look at to check why clock is not initiating.
