Use when debugging Cortex-R5 or Cortex-R firmware — TCM, MPU, caches, DFSR/DFAR aborts, exceptions, GIC/VIC interrupts, lockstep or split mode, ECC, or JTAG bring-up
Use when integrating or debugging heatshrink embedded compression — encoder/decoder sink/poll/finish loops, window/lookahead sz2, HSER/HSDR codes, or static vs dynamic alloc
Use when integrating, porting, or debugging micro-ecc (uECC) ECDH, ECDSA, key generation, uECC_set_rng, signatures, curve selection, or key/signature byte formats on an MCU
Use when debugging OpenOCD, J-Link, ST-Link, CMSIS-DAP, probe connection, reset scripts, flash algorithms, GDB attach, semihosting, RTT, or SWD/JTAG failures
Use when integrating, refactoring, or debugging PLOOC object-oriented C - def_class encapsulation, private_member protection, vtable dispatch, or inheritance-style structs
Use when integrating or debugging Li-ion charger/fuel gauge ICs (BQ24295, BQ27441, MAX17048) over I2C, covering charge start, watchdog host mode, NTC/JEITA faults, and SOC jumps
Use when integrating or debugging cellular AT modems (Quectel, SIMCom, u-blox) over UART for CREG/CEREG registration, CGDCONT APN/PDP, TCP/UDP sockets, or URC parsing
Use when integrating a UART GNSS/GPS module (u-blox M8/M9/M10, Quectel Lxx), parsing NMEA GGA/RMC/GSA/GSV or UBX-NAV-PVT, or debugging no-fix, TTFF, checksum, or PPS issues
