Board details

A service manual is available at electronica-pt.com, schematics can be downloaded from ElektroTanya.

  • After adding two resistors, RX_STBY and TX_STBY can be accessed on pins 10 and 12 of the (hidden) SCART connector footprint.
  • These signals are connected to pins STBC_UART_1_RX and STBC_UART_1_TX of the Novatek SoC.
  • Code and data in SPI flash can be changed, there is no verification.

Building a SCART debug cable (17MB211 only)

  • Take a 3.3V serial adapter
  • Take a SCART cable
  • Connect a ground signal (e.g. 14) to the serial adapter's ground
  • Connect pin 12 (TX_STBY) to the serial adapter's RX line
  • Connect pin 10 (RX_STBY) to the serial adapter's TX line
