Getting Started with Flux

aa error step by step clear karo 16 capacitor MPN findings, 10 IMU/USB ERC errors અને છેલ્લી routing તપાસના 67 airwires બાકી છે. આગળ capacitorsની evidence-based qualification અને routing blockerનો સુધારો જરૂરી છે;

હું ક્રમ પ્રમાણે પહેલાં 16 capacitors qualify કરીશ, પછી IMU/USB ERCનાં સાચાં કારણ તપાસીશ, અને છેલ્લે routing blocker પર કામ કરીશ. દરેક તબક્કાનો સુધારો save કરીને fresh count ચકાસીશ; errors છુપાવીશ નહીં.

Step-by-step કામ ગોઠવીને પહેલા બાકી 16 capacitorsની qualification શરૂ કરી, પરંતુ તેનું અંતિમ પરિણામ વાંચીને verify કરી શક્યો નથી—તેથી આ sessionમાં capacitor errors ઘટ્યા કે નવા MPNs save થયા હોવાનો દાવો નથી.

છેલ્લી verified સ્થિતિ: 16 capacitor MPN findings, 10 IMU/USB ERC errors અને 67 airwires બાકી છે; અગાઉ qualify કરેલા 36 resistors અને saved routing યથાવત્ છે. આગળ capacitor qualificationનું પરિણામ તપાસવું, પછી ERCનાં સાચાં કારણ સુધારવાં અને routing blockers ઉકેલવા જરૂરી છે; board હજી flight-ready નથી.

Targeted Routing Continuation

Scope and fresh measurements — 2026-10-11

Current project: repevok665/f405-flight-controller-prototype. Initial live routing_state: 76 airwires, independently corroborated by DRC at05:01:03Z. Final live routing_state: 67, independently corroborated by DRC at05:08:42Z. Reduction: 9.

Table

Check category	Initial	Final
DRC Airwire Errors	76	67
Other DRC Errors in Error/Warning filter	0	0
DRC redundant-trace Warnings	1	1
Placement Warnings	5	5
ERC Errors	10	10

Four successful routing mutations persisted nine island joins; seven additional calls saved no copper. Ten named nets selected, eleven calls total (IMU_CLKIN alone tried twice); no connection exceeded two blocked attempts. No convergence block was returned. Final read-only inspection confirms the successful copper persists. Bounded batch completed; overall layout incomplete.

Atomic rejection cases MOTOR1/CURRENT_DIVIDED/ADC_VBAT: router did not identify newly disconnected pins. Exact root cause uncertain; requires geometry/connectivity inspection rather than repetition or suppression of airwire checks.

Preserved constraints and unresolved gates

39×39mm rectangular outline confirmed live. Applied Standard Density SDI v3 profile and JLC3313 four-layer stackup retained. No netlist, clearances, footprint, placement, manufacturing rule or stackup mutation. Existing design-rule widths used; same-net via-pad policy copper-clearance. No copper deleted or rerouted. Top0°/Bottom90° orientations and established Top critical-net preferences passed on every call; inner plane layer purposes unchanged. Router selected some inner-layer signal segments, as blocker evidence shows; continuous ground-plane coverage/return paths are not qualified by this DRC result and require later review.

Protected USB group52889a90-0993-479b-a194-07d0cdca310b/5cc73652-28d0-412e-8a22-5eaa03641ad1/ce236b62-82d0-41ea-8e92-443aaf72f9d0 retained, including its redundant warning. Initial preflight returned four USB differential feasibility Warnings: two D2 I/O1/I/O2 pairs and J1 DP1/DN2,DP2/DN1. No USB/rule correction attempted because protected geometry and clearances must remain; these remain separate USB/bulk-routing gates, not proof independent nets cannot route. Existing escapes/neckdowns retained; no global neckdown regeneration performed.

Final placement warnings remain density plus D8–J3(8.43mm²), D8–J7(3.35mm²), F2–J7(0.47mm²), U3–J5(5.20mm²). Final ERC remains U2:VDD/VDDIO undriven on3V3_IMU and eight J1 power-input undriven findings (shell/ground/VBUS). None concealed or suppressed.

Next safe action

Keep all successful copper. Diagnose atomic airwire rejections before retrying their batches. Review local via escapes around R4/C7/C14/C21/C22/R33 and IMU_INT/power copper before selecting a specific minimal placement adjustment; no guaranteed move established in this pass. Review MOTOR2's49.351mm detour and inner-plane return continuity rather than treating mere connectivity as flight qualification. Separate protected USB repair remains outstanding. Hardware, flight and55A ESC tests cannot be performed here and were not performed; no manufacturing or flight readiness claimed.
