keil-mdk-build skillA
keil-mdk-build is agent-read markdown (skill) from amethystluna/embedded-workbench: Use when building, flashing, or packaging firmware with Keil MDK (UV4 CLI, ARMCLANG), analyzing .map files for ROM/RAM optimization and memory budget, or diagnosing Keil-specific build failures. NOT for non-Keil build systems (Makefile, CMake, IAR, GCC-only). For crash triage see hardfault-triage..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
<HARD-GATE>
This is a domain implementation skill. If you are planning, designing, or entering plan mode — load `Skill("embedded-workbench")` first to activate the workflow gates (Plan Verification Gate, Approval Gate, Closure Gate). Domain skills carry implementation guidance, not workflow enforcement.

# Keil MDK Build
Patterns for building embedded firmware with Keil MDK. Covers both ARM Compiler 5 (armcc) and ARM Compiler 6 (armclang).
## UV4 CLI Build (Authoritative)
UV4.exe batch mode is the canonical build path. The Python CLI reimplementation is useful for CI but may miss include paths.
```powershell
<Keil>\UV4\UV4.exe -b project.uvprojx -t TargetName -j0 -o <log_path>
```
Replace `<Keil>` with the Keil install root. Auto-discover by checking common locations or ask the user when unknown.
**Flags**:
| Flag | Meaning |
| ---- | ------- |
| `-b` | Batch mode (no GUI) |
| `-t <target>` | Target name within the multi-target project |
| `-j0` | Auto-parallelism (use all cores) |
| `-o <path>` | Log output file |
**Exit codes**:
| Code | Meaning |
| :--: | ------- |
| 0 | Success (no errors, no warnings) |
| 1 | Warnings but no errors |
| 2 | Errors |

How to install
mdr add amethystluna/embedded-workbench/keil-mdk-build@git:20260626.c525f3fmdr add amethystluna/embedded-workbench/keil-mdk-build@sha256:f636d04b931fcb9fPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
