# Current RX task

TASK =
|
|
VERIFY RF-001A SLAVE CLKIN
|
|
|
|
The main PC has already completed the official source-side command for MASTER serial `000000000000000097c063dc323b97d3`:
|
|
|
|
```powershell
|
|
hackrf_clock.exe -d 000000000000000097c063dc323b97d3 -o 1
|
|
```
|
|
|
|
The command returned exit code 0. Treat this as `MASTER CLKOUT COMMAND = PASS`. Do not use `hackrf_clock -r 3` or Si5351 register 29 as a blocking test of physical CLKOUT. The common clock is still unverified until this RX task confirms the signal at SLAVE CLKIN before and after a short RX-start. RF TX remains 0.
|
|
|
|
1. In the project path from RX_NODE_STATE.md, record `git status --short --untracked-files=no`, branch and HEAD. Require a clean tracked checkout and branch `video-development`. Run `git pull origin video-development`; then require local HEAD = `origin/video-development`. Do not commit or push.
|
|
|
|
2. Run `hackrf_info` with the verified local host tools and preserve its complete stdout. Require exactly this RX serial:
|
|
|
|
```text
|
|
000000000000000097c063dc2e5327d3
|
|
```
|
|
|
|
Stop if the device is absent or the serial differs. Do not change firmware, CPLD, USB drivers or Zadig.
|
|
|
|
3. With the physical cable connected from MASTER CLKOUT to SLAVE CLKIN, run the official partner-side check with the explicit RX serial and preserve complete stdout:
|
|
|
|
```powershell
|
|
& '<verified hackrf_clock.exe path>' -d 000000000000000097c063dc2e5327d3 -i
|
|
```
|
|
|
|
Accept only the exact line `CLKIN status: clock signal detected` as `SLAVE CLKIN BEFORE RX = DETECTED`. If the signal is not detected, set `COMMON CLOCK RX VERIFIED = NO` and stop. Do not alter clock configuration automatically.
|
|
|
|
4. If CLKIN was detected, perform one short, finite RX-start on SLAVE. This opens receive mode only; it does not transmit and does not create the 20-second capture:
|
|
|
|
```powershell
|
|
& '<verified hackrf_transfer.exe path>' -d 000000000000000097c063dc2e5327d3 -r NUL -f 1400000000 -s 8000000 -n 65536 -l 0 -g 0 -a 0 -p 0 -B
|
|
```
|
|
|
|
Require exit code 0 and a complete transfer of 65536 complex samples. Record all reported overruns and errors. Any nonzero overrun, USB error, incomplete transfer or nonzero exit code means `SHORT RX START = FAIL` and stops the task.
|
|
|
|
5. Immediately after the short RX-start, repeat the same explicit `hackrf_clock.exe ... -i` command and preserve complete stdout. Require the exact line `CLKIN status: clock signal detected`. Set `COMMON CLOCK RX VERIFIED = YES` only when CLKIN was detected before RX, the short RX-start passed, and CLKIN remained detected after RX.
|
|
|
|
6. Register 29 may be read only as optional diagnostic information with the already verified read-only command. It is not a PASS/FAIL criterion. Do not use `hackrf_debug` to write registers. Do not use `hackrf_clock -r 3` as a blocking criterion.
|
|
|
|
7. Set `RX READY TO CAPTURE = YES` only if the branch/HEAD checks, RX serial check and all three clock checks in step 5 pass. This readiness does not authorize a capture or transmission. Do not start the 20-second RF-001A capture, RF TX, continuous RX, RF-001B, firmware/CPLD updates, `hackrf_spiflash`, Zadig or USB driver changes.
|
|
|
|
8. Finish with this exact report and STOP:
|
|
|
|
```text
