DSO2512G "mod" firmware

Modified DSO2512G V1.3.0C firmware for PCB V9.1, V9.13, V9.14 and V9.15.

Changes:

  • Extra menu accessible by long pressing the MENU key.
  • USB serial mode for communicating with PC.
  • New small/large fonts.
  • New menu bitmaps.
  • New icon bitmaps.
  • USB disk with .bmp files also contains .wav files with the system parameters, waveform, and measurement data.
  • Signal generator supports custom extra waveforms.
  • Extra key shortcuts for the signal generator.
    • S = increase duty cycle by 5%
    • NS = decrease duty cycle by 5%
    • POWER+UP = previous hz/khz/mhz unit
    • POWER+DOWN = next hz/khz/mhz unit
  • Removed CH2 50% alignment offset.
  • Fixed "bouncing" horizontal cursor at outer left and right position.
  • Fixed "long press s" key conflict between zoom mode toggle and measurement background color change.
  • Show FFT frequency in Log and Linear FFT mode when horizontal cursor is enabled.
  • Show "REF" text when reference waveform is active.

How to install: the usual procedure. You also need to (somehow) upgrade the FPGA firmware if you upgrade from a firmware older than V1.2.9C to V1.3.0C or else you will have AUTO issues.

How to unlock SPI dump

The bootloader locks the firmware to the unique ID of the SPI flash chip on first boot, so if you want to use a SPI flash dump of someone else, you first need to unlock it by overwriting part of the dump with these values:

0F000: FF FF FF FF FF FF FF FF FF FF FF

30000: 06 00 00 EA 65 47 4F 4E

Also, the unlocked dump will boot to the original old/factory ARM firmware, not the new/upgraded ARM firmware.
