SOP Boot Modes

Sense-on-Power — pins latched at nRESET 0→1; never change at runtime
001
Functional / Flash-Boot
Normal steady-state operation. Boots firmware from QSPI flash. MSS Logger output active.
010
Flash Programming
UART download mode. AM62 asserts UART break → streams metaImage via UniFlash or mmWave SDK flash tool on Control UART.
flash command
# SOP[2:1:0] = 010, UART break, then stream
python3 mmwave-sdk/tools/flash/UniFlash.py \
  --port /dev/tty.usbserial-XXXXX \
  --image metaImage.bin
100
Debug / Development
JTAG + CCS attach mode. Used during IWR6843AOP firmware development with XDS110 probe.
