fix(pdb): Read the bricks on the pages the datasheet actually specifies
Every PDB reading came back NA, and the cause was a base error. The four
ADPM12200 bricks put each measurement on its own PMBus PAGE, written
before the read. The bring-up spreadsheet listed those page numbers in
decimal but with an 0x prefix:
Vin PAGE 9 -> it said 0x00 (0x09)
Iin PAGE 10 -> it said 0x10 (0x0A)
Vout PAGE 2 -> it said 0x02 correct by luck
Iout PAGE 14 -> it said 0x14 (0x0E)
Temp PAGE 18 -> it said 0x18 (0x12)
Only Vout worked, because 2 reads the same in either base. Hence Iin and
Iout answering 0xFFFF, Temp answering 0x0000, and a Vin scale factor
having to be invented to make 50 V appear out of a page-0 register.
pwr_brick.sh reads all five bricks with the right pages and the
datasheet's DIRECT equation, X = (1/m)(Y x 10^-R - b): voltage Y x 8 mV,
current Y x 0.04 A, temperature Y x 0.01 C. Cross-checked rather than
assumed - READ_VOUT 0x05D4 decodes to 11936 mV, exactly what
'show platform voltage' reports for that rail through a separate sensor
path. The datasheet is committed alongside so the numbers are checkable.
Left flagged: Table 3 does not list READ_VIN or READ_IIN. They borrow the
voltage and current coefficients here, which is consistent with a ~50 V
input but is not something the datasheet states.
Each value is re-read until it passes three checks: not 0xFFFF, not
0x0000, and inside a plausibility window. The window is the one that
matters - this bus corrupts the HIGH BYTE only, which turns 11.98 V into
32.00 V. Positive, plausible in magnitude, and invisible to any all-ones
filter. 0x0000 is rejected for the mirror-image reason: on the
temperature register it decodes to a believable 0 C.
Adds comboA/comboB margin profiles per board. comboB is comboA with every
direction flipped, so the pair covers each rail high and low while its
neighbours sit the other way. NC channels stay nominal in both - there is
nothing to margin on an unused rail.
Script C re-enables the BMC USB journalctl dump, which had been commented
out, so that service log now reaches the master log.
Script A -> V1.1.6.

# v1.1.6 — The PDB bricks were never being asked the right question
|
||||||
|
|
||||||
|
## 🐛 Bug fixes
|
||||||
|
|
||||||
|
**Every PDB reading was `NA`, and the cause was a page number written in the wrong base**
|
||||||
|
* The four ADPM12200 bricks put each measurement on its own PMBus PAGE, and the page has to be written before every read. The bring-up spreadsheet listed those page numbers in decimal but with an `0x` prefix, so four of the five selected the wrong page:
|
||||||
|
|
||||||
|
| Reading | Datasheet PAGE | Should send | Spreadsheet said |
|
||||||
|
|---|---|---|---|
|
||||||
|
| Vin | 9 | `0x09` | `0x00` |
|
||||||
|
| Iin | 10 | `0x0A` | `0x10` |
|
||||||
|
| Vout | 2 | `0x02` | `0x02` ✅ |
|
||||||
|
| Iout | 14 | `0x0E` | `0x14` |
|
||||||
|
| Temp | 18 | `0x12` | `0x18` |
|
||||||
|
|
||||||
|
* Only Vout worked — because 2 reads the same in either base. That is why Iin and Iout answered `0xFFFF` and the temperature answered `0x0000`, and why a Vin scaling had to be invented to make 50 V appear.
|
||||||
|
* `blanton_pwr_data.sh` sends no page at all (its PDB table has `page "-"`), which is the reason it reports the whole PDB section as `NA`.
|
||||||
|
|
||||||
|
## ✨ New features
|
||||||
|
|
||||||
|
**`pwr_brick.sh` — the five power bricks, read properly**
|
||||||
|
* `show` prints Vin / Iin / Vout / Iout / Temp for all five: `SWB0.PU207` (0x62), `SWB0.PU13` (0x63), `SWB1.PU332` (0x60), `SWB1.PU85` (0x61) and `CPB.PU37` (0x26). `-r` adds the raw words.
|
||||||
|
* Conversions come from the datasheet's DIRECT equation, `X = (1/m)(Y × 10⁻ᴿ − b)`, with Table 3's coefficients: voltage `Y × 8 mV`, current `Y × 0.04 A`, temperature `Y × 0.01 °C`.
|
||||||
|
* **Cross-checked, not assumed**: `READ_VOUT` returns `0x05D4` → 1492 × 8 = 11936 mV, which is exactly the figure `show platform voltage` reports for that rail from a completely separate sensor path.
|
||||||
|
* `CPB.PU37` is a different part — no page writes and its own scaling — and is handled separately.
|
||||||
|
* The datasheet is now in the repo (`docs/ADPM12200CMLZxx_DS_*.pdf`) so the pages and coefficients can be checked without hunting for it.
|
||||||
|
|
||||||
|
**Every value is validated before it is printed**
|
||||||
|
* This bus corrupts the **high byte only**. That turns `11.98 V` into `32.00 V` — positive, plausible in magnitude, and invisible to any "reject 0xFFFF" filter. Each value is re-read (up to `PB_TRIES`, default 8) until it is not `0xFFFF`, not `0x0000`, and lands inside a plausibility window.
|
||||||
|
* `0x0000` is rejected as a raw word for the same reason: on the temperature register it decodes to a perfectly believable 0 °C.
|
||||||
|
|
||||||
|
**Complementary margin profiles per board**
|
||||||
|
* `comboA` / `comboB` for CB and each SWB CONN. `comboB` is `comboA` with every direction flipped, so running both covers each rail high and low while its neighbours sit the other way.
|
||||||
|
* NC channels stay at `nominal` in both — there is nothing to margin on an unused rail (CONN14 CH10/11/13, CONN15 CH10).

**After copying to the DUT:**
|
||||||
|
|
||||||
|
```bash
|
||||||
|
chmod +x ~/Blanton_Script/*.sh # see below
|
||||||
|
grep -rlU $'\r' ~/Blanton_Script # expect no output

|
```

||||||
|
|
||||||
|
`blanton_ber.sh`, `nfc_polling.sh`, `blanton_tr518.sh`, `blanton_multiphase_margin.sh`, `pwr_brick.sh` and the two `TH6_SWB*_power_readback.sh` are invoked through `./` or `~/`, so they need the execute bit along with `bmc_monitor.sh` and `usb_target.sh` — neither git nor a Windows/USB copy carries it reliably.
|
||||||
|
|
||||||
|
## ⚠️ Before you run
|
||||||
|
|
||||||
|
* **`READ_VIN` and `READ_IIN` are not in the datasheet's coefficient table.** They are decoded here with the voltage and current coefficients — consistent with a ~50 V input, but not stated by the datasheet. Anything quoting brick Vin should have that confirmed first. `PB_VIN_M` / `PB_IIN_M` are where to change it.
|
||||||
|
* **`NA` has two meanings**: nothing readable, or read but outside its plausibility window. Use `PB_TRIES=1 ./Blanton_Script/pwr_brick.sh show -r` to see the unretried raw words and tell them apart.
|
||||||
|
* **Margin profiles are positional.** `comboA_SWB_CONN13` applied to a CONN16 board margins the wrong rails and nothing detects it.
|
||||||
|
* **`blanton_multiphase_margin.sh save` is permanent**, and it must not be mixed with `margin.sh` — same rails, two access paths, no interlock.
|
||||||
|
* **A soak longer than 24 hours needs the stress runtimes raised** — `--runtime 86400` is a ceiling.
|
||||||
|
* **Script 4 (thermal/safety) has no teardown** — finish with `blanton_tr518.sh stop` and `kill $(jobs -p)`.
|
||||||
|
* **These three cannot share the switch**: `blanton_ber.sh`, `blanton_tr518.sh`, `blanton_traffic_linespeed`.
|
||||||
|
* **`FAN_SPEED` is 100.**
|
||||||
|
* **The three items listed as unverified in v1.1.0 are still unverified**: the `ce0` ingress mirror, the 120s settle in `blanton_tr518.sh`, and `test mode nr=no` on stop.

# =============================================================================
|
||||||
|
# Version History:
|
||||||
|
# V1.1.0 2026-09-02 PAGE values and conversions taken from the ADPM12200
|
||||||
|
# datasheet instead of the bring-up spreadsheet.
|
||||||
|
# The spreadsheet wrote every PAGE in decimal but with an
|
||||||
|
# 0x prefix, so four of the five selected the wrong page:
|
||||||
|
# Vin PAGE 9 -> it said 0x00 (should be 0x09)
|
||||||
|
# Iin PAGE 10 -> it said 0x10 (should be 0x0A)
|
||||||
|
# Vout PAGE 2 -> it said 0x02 correct by luck
|
||||||
|
# Iout PAGE 14 -> it said 0x14 (should be 0x0E)
|
||||||
|
# Temp PAGE 18 -> it said 0x18 (should be 0x12)
|
||||||
|
# Only Vout worked, because 2 reads the same either way.
|
||||||
|
# That is why Iin/Iout answered 0xFFFF and Temp 0x0000.
|
||||||
|
# Conversions now use the datasheet DIRECT equation; the
|
||||||
|
# reverse-engineered BRICK_VIN_LSB is gone.
|
||||||
|
# V1.0.0 2026-09-02 First version.

#
|
||||||
|
# Path: CB FPGA F3 VI2C ch4 -> TCA954x mux 0x72 ch0 -> the bricks
|
||||||
|
#
|
||||||
|
# The four ADPM12200 modules put each measurement on its own PMBus PAGE, so a
|
||||||
|
# PAGE write has to precede every read. blanton_pwr_data.sh does not send one
|
||||||
|
# at all (its PDB table has page "-"), which is why it reports them as NA.
|
||||||
|
#
|
||||||
|
# READ_VIN 0x88 PAGE 9
|
||||||
|
# READ_IIN 0x89 PAGE 10
|

|
# READ_VOUT 0x8B PAGE 2
|
||||||
|
# READ_IOUT 0x8C PAGE 14
|
||||||
|
# READ_TEMPERATURE_1 0x8D PAGE 18
|

|
#
|
||||||
|
# DIRECT format, datasheet Table 3 ("PMBus Command Code Coefficients"):
|
||||||
|
#
|
||||||
|
# X = (1/m) x (Y x 10^-R - b) Y = the 2-byte two's complement word
|
||||||
|
#
|
||||||
|
# Voltage m=0.125 b=0 R=0 units mV -> X = Y x 8 mV
|
||||||
|
# Current m=0.25 b=0 R=2 units A -> X = Y x 0.04 A
|
||||||
|
# Temperature m=1 b=0 R=2 units degC -> X = Y x 0.01 degC
|
||||||
|
#
|
||||||
|
# Sanity check: READ_VOUT 0x05D4 = 1492 -> 1492 x 8 = 11936 mV, which is exactly
|
||||||
|
# what PDB_IBC_SWB1_A_VOUT reports in 'show platform voltage'.
|
||||||
|
#
|
||||||
|
# ⚠️ Table 3 does not list READ_VIN or READ_IIN. They are decoded here with the
|
||||||
|
# Voltage and Current coefficients respectively - reasonable, and consistent
|
||||||
|
# with a ~50 V input, but not stated by the datasheet. PB_VIN_M / PB_IIN_M
|
||||||
|
# below are where to change that if the part turns out to differ.
|
||||||
|
#
|
||||||
|
# ⚠️ CPB.PU37 (0x26) is a DIFFERENT part: no PAGE writes, and its own scaling
|
||||||
|
# (Vin 0.25 V, Vout 2^-11 V, Iout 0.5 A per count of the mantissa). Those
|
||||||
|
# three were confirmed against words this DUT returns.
