Components and source info

I’ve been looking over the source code and just wanted to verify some parts of the design, so I don’t delve into the technical details of the wrong components.

  • CPU used is i.MX RT1051
  • CPU and memory layout compatible with IMXRT1050-EVKB
    • NOR flash via flexSPI to CPU (bootloader? execute in place)
    • adds EEPROM is M24256 via I2C to CPU (purpose?)
    • adds eMMC (primary OS and user storage?)
  • Cellular module is Quectel LTE EG-25G via UART (+ GPIOs) to CPU
  • eInk display is ED028TC1 (480x600 pixels of 4-bit monochrome) via SPI to CPU
  • some bluetooth module via UART
  • other boring components

I’ve also noticed “fsl” is everywhere in low level parts of the source code. Is this short for “Freescale Semicondutor Library”?

And yes fsl stands for exactly that :slight_smile:
