 # hbox_v5_bringup — EinarBoard v5 first-flash bring-up firmware
 
 Bench-proves a newly assembled v5 board over USB-C **J11** only. Never powers the RTK stack.
-Bench mode (0.2.0): `P`+`Y` stack ON/OFF, `n` NMEA monitor (fix 4 = RTK FIX).
+Bench mode: `P`+`Y` stack ON/OFF, `n` NMEA monitor (fix 4 = RTK FIX). Console (0.2.1): CR+LF lines, `EVT` on every state change, named `STAT` every 5 s, `$PHLG` every 10 s in the fleet v3.x layout (server-parseable).
 Checks: HSE 25 MHz + USB CDC · LSE Y4 · I2C: PCF8574 0x20 / SHT40 0x44 / TMP102 0x48 /
 SC16IS752 0x4D · gauge + RGB LED walk · ADC · digital inputs. Prints PASS/FAIL, then a

 ## Changelog
+- **0.2.1** (2026-09-17): console made monitorable — every line ends CR+LF (no more PuTTY staircase); `EVT up=…` line on every
+  state change (stack ON/OFF with reason and the expected voltages, ignition edge, 5 V present/lost, charger status/fault edges,
+  first NMEA frame / NMEA lost >5 s, GGA fix-quality change, stack refused/cancelled); `STAT` every 5 s with named values
+  (`ign=ON`, `chrg=idle`, `flt=none`, `tntc=n/c`, `i2cerr=`, `t_on=`, `nmea=`/`bad=`); `$PHLG` every 10 s + after each stack change,
+  **same 24-field layout + XOR checksum as fleet fw v3.x** (verified against `htracker/retranslator.py::_parse_phlg`; `fw=0.2.1-bu`,
+  `state=BENCH|RUN`, `link=SRCH|DEGR|OK`); NMEA checksum verified (bad frames counted as `rxbad`); `P` arms non-blocking (10 s window),
+  `Y` confirms; new commands `t` ($PHLG now), `l` (field legend), `v` (multimeter checkpoints for the stack gate: SYS5V/PWR_CTRL/GATE_LS/SW_5V);
+  stack auto-OFF if 5 V is lost; `v5=…(BAJO)` + EVT when VEH5V drops under 4.6 V (LTC4040 PFI zone: PFI divider R51 270k/R52 100k
+  → 4.44 V falling, backup VSYS 4.79 V via R53 499k/R54 100k) — the 24-Jul modem-hiccup mechanism, now visible in the log. Build: no-op ctags + explicit definition order (arduino/ctags unreachable from the build host).
 - **0.2.0** (2026-09-17): bench mode for the assembled unit — `P`+`Y` powers the RTK stack (only with 5 V on P2),
   `P` again turns it off; `n` streams `$GxGGA` from the simpleRTK2B UART1 (PA3, 115200) for 20 s with fix/sats/HDOP;
   `STAT` shows `stack=` and the last GGA. Charge stays disabled, K1 released. Uses the core's `Serial2` (USART2).
