Modding

In stock configuration both FX2LP and FPGA boots from their serial EEPROMs, but with a small hw patch it is possible to boot both parts from PC:

  • lift U3 pin 5 to disable FX2LP EEPROM boot
  • remove R102 and solder it between R102's left pad (this is FPGA's M1 pin) and C135's left pad (this is Vcc) to switch FPGA config mode to Slave Serial. FX2LP's PC5 is FPGA's PROGRAM_B, PC3 is DATA, PC1 is CLOCK, PC0 must be driven high (this is SPI FLASH nCS)

4032L's current consumption is well within the 0.5A USB 2.0 limit, so it's possible to toss the wall brick and convert the LA to USB power:

  • solder a jumper in unpopulated R279 position
  • cover the external power connector with some sticker to prevent simultaneous power accidents
