PDX2000 Firmware Upgrade

The PDX2000/PDX2300 and PDX3000 turntables are very similar in terms of circuitry - really the only difference is in the main MCU.

The main guide is in this video.

• Modify the main circuit board :
  • Replace the MCU (QU01) with a HD64F3052F25 (available used from utsource)
  • Replace the Crystal (XU01) with a 25MHz one
  • (If you have a PDX2300) add the components RU02 (4.7KOhm) and RU27 (100Ohm). (Or just bridge their pads with solder, that's probably OK too)
  • Cut this trace on the bottom of the board to disconnect pin1 from VCC :
    • 

• Build a programming cable using an 8-pin JST PH connector and some dupont wires, this is the wiring for it :
  • 

• Connect a USB-TTL serial adapter to your PC, and connect it to JU05 (FLASH) on the Vestax PCB using the cable you just made
• Install the renesas flash tools - you want the "[Evaluation Software] Flash Development Toolkit V.4.09 Release 03"

• Run Flash Development Toolkit 4.09 Basic.
  • Go to "Options->New Settings" (it might automatically do this the first time you start it)
  • Type "H8/3052" in the filter box and select the first option in the list, click next
  • Select the COM port of your USB serial adapter (you can find this in Device Manager), click next
  • Set the CPU crystal frequency to 25MHz, click next
  • Make sure BOOT Mode and Use Default is selected, click next
  • Click Finish
  • Download the modified PDX3000 firmware, and load it into the "User/Data Area" box of the Flash Development Toolkit
  • Click "Program Flash", it will take 10 seconds or so.
  • If all is ok, it will say "Image written to device" in green - if not, check your connections and soldering
