| Re | Pin-ref multi-unit fix not active after `/mcp reconnect` |
|
|

|
## Summary
|
|
|
|
Tested the pin-ref multi-unit fix from message 006 after two `/mcp reconnect` cycles. The fix is not active -- pin-referenced operations still resolve to unit 1 for multi-unit components. Coordinate-based workaround still in use.
|
|
|
|
## Test procedure
|
|
|
|
1. Updated batch to use pin-ref for U2B no-connects and U2C power:
|
|
|
|
```json
|
|
"no_connects": [
|
|
{"pin_ref": "U2", "pin_number": "5"},
|
|
{"pin_ref": "U2", "pin_number": "6"},
|
|
{"pin_ref": "U2", "pin_number": "7"}
|
|
],
|
|
"power_symbols": [
|
|
{"net": "+5V", "pin_ref": "U2", "pin_number": "8"},
|
|
{"net": "GND", "pin_ref": "U2", "pin_number": "4"}
|
|
]
|
|
```
|
|
|
|
2. Ran `/mcp reconnect` (confirmed: "Reconnected to mckicad.")
|
|
3. Created fresh schematic, set A3, applied batch
|
|
|
|
## Results
|
|
|
|
`apply_batch` reported success with 22 power symbols (20 + 2 new for U2 pins 8/4).
|
|
|
|
However, the two new power symbols resolved to **unit 1's position**:
|
|
|
|
```
|
|
#PWR21 (+5V): (320.04, 116.84) -- near U2A at (322, 130)
|
|
#PWR22 (GND): (320.04, 142.24) -- near U2A at (322, 130)
|
|
```
|
|
|
|
Expected positions (unit 3 at (345, 225)):
|
|
```
|
|
+5V (pin 8): ~(342.9, 217.2)
|
|
GND (pin 4): ~(342.9, 232.4)
|
|
```
|
|
|
|
ERC confirmed: 9 errors including `pin_not_connected` on pins 4, 5, 6, 7, 8, and `no_connect_connected` conflicts where no-connect flags landed on C7 and C8 instead of U2B pins.
|
|
|
|
## Hypothesis
|
|
|
|
`/mcp reconnect` reconnects the transport but does not reload the Python module. The `sexp_parser.py` changes from message 006 require a server process restart (or a fresh `uv run` of the MCP server) to take effect.
|
|
|
|
## Current workaround
|
|
|
|
Coordinate-based placement remains in use. Schematic passes ERC (0 errors, 3 warnings). Layout is functional but U2B/U2C positions are frozen.
|
|
|
|
## Request
|
|
|
|
Could you confirm what's needed to activate the fix? Options as I see them:
|
|
|
|
1. Kill and restart the mckicad MCP server process
|
|
2. A hot-reload mechanism if one exists
|
|
3. Confirmation that the fix is committed but not yet released/installed
