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”?
