Application processor booting LinuxSTM32MP157AAB3stm32mp157aab3
STM32MP157AAB3 (LFBGA354)
Application processor: 2× Cortex-A7 at 650 MHz (NEON, VFPv4), Cortex-M4 at 209 MHz, 3D GPU, LTDC display controller, 16-bit DDR3/DDR3L/LPDDR2/LPDDR3 interface, 3× SDMMC, USB, Ethernet. LFBGA354 package: 98 GPIOs. The symbol is split into five units (power, DDR, GPIO A–C, GPIO D–H, system). Pins and balls from ST's pin database, checked against the KiCad library. Board design: the 0.8 mm BGA needs 4 or more layers with vias between the balls (DS12504 table 121); the DDR3L lines need length-matched byte lanes and controlled impedance (ST application note AN5122).

Simulation model
An emulated application processor (both CPU cores, MMU, interrupt controller, timers and the on-chip peripherals) boots the boot loaders and Linux from the SD-card image. The serial console is the terminal of the part; the GPIO pins are pins of the analog circuit.
