From 0e3463df39fa86b306b938494e8539fc758fe36c Mon Sep 17 00:00:00 2001 From: "OpenClaw (Siggi)" Date: Sun, 1 Mar 2026 18:45:19 +0000 Subject: [PATCH] Complete documentation update for UT project MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Major changes based on user requirements: 1. Board identification: TQMa6UL (from sticker TQMA6U-AB) - Old code reference 'tqma6x' = generic i.MX6 family - Machine: tqma6ulx-mba6ulx 2. Build name: UT (Universität/Projekt) - All documentation updated with UT branding - Build directory: build_ut 3. ci-meta-tq workflow: - Replaced manual layer cloning with official TQ CI repo - Uses git submodules for all layers - ci/fill_mirror script for mirror population 4. License tables in 3 formats: - CSV: UT-license-table.csv - Markdown: license-summary.md - Excel-compatible: UT-license-table-excel.md 5. Air-gap deployment: - Complete offline build instructions - /srv/yocto/ premirror setup - BB_NO_NETWORK configuration 6. 2038 compliance: - Verified: Kernel 6.6 + glibc 2.38 - 64-bit time_t on 32-bit ARM - Scarthgap 5.0 LTS confirmed suitable All documents ready for mirror creation and approval process. --- .../step-by-step-mirror-creation.md | 473 ++++++++++-------- .../UT-license-table-excel.md | 19 + docs/03-license-analysis/UT-license-table.csv | 18 + docs/03-license-analysis/license-summary.md | 154 ++++++ .../corporate-network-deployment.md | 380 +++++++------- 5 files changed, 615 insertions(+), 429 deletions(-) create mode 100644 docs/03-license-analysis/UT-license-table-excel.md create mode 100644 docs/03-license-analysis/UT-license-table.csv create mode 100644 docs/03-license-analysis/license-summary.md diff --git a/docs/02-mirror-creation/step-by-step-mirror-creation.md b/docs/02-mirror-creation/step-by-step-mirror-creation.md index 1006988d..09f41fdf 100644 --- a/docs/02-mirror-creation/step-by-step-mirror-creation.md +++ b/docs/02-mirror-creation/step-by-step-mirror-creation.md @@ -1,10 +1,25 @@ -# Step-by-Step Yocto Mirror Creation +# Step-by-Step Yocto Mirror Creation with ci-meta-tq -**Document ID:** PROC-MIRROR-001 +**Document ID:** PROC-MIRROR-001-REV2 **Date:** 2026-03-01 **System:** Ubuntu 22.04 LTS -**Environment:** Outside corporate network (Internet access required) -**Target:** TQMa6UL Yocto Scarthgap mirror for offline deployment +**Environment:** Outside corporate network (Internet required) +**Target:** TQMa6UL Yocto Scarthgap mirror (UT build) +**Build Name:** UT (Universität/Projekt) + +--- + +## Hardware Target Confirmation + +Based on sticker analysis and code review: + +**Sticker:** TQMA6U-AB RK REV.0405 +**Board:** TQMa6UL (NXP i.MX6 UltraLite, Cortex-A7, 32-bit) +**Carrier:** MBa6x +**Code Reference:** `tqma6x` = generic i.MX6 family identifier in legacy codebase + +**Machine Configuration:** `tqma6ulx-mba6ulx` +*Alternative (ci-meta-tq multi-config):* `tqma6qdl-multi-mba6x` --- @@ -15,10 +30,10 @@ | Resource | Minimum | Recommended | Notes | |----------|---------|-------------|-------| | CPU | 4 cores | 8+ cores | Parallel builds | -| RAM | 8 GB | 16+ GB | BitBake is memory-intensive | +| RAM | 8 GB | 16+ GB | BitBake memory-intensive | | Disk Space | 100 GB | 200+ GB | Sources + build artifacts | | OS | Ubuntu 22.04 | Ubuntu 22.04 LTS | Verified platform | -| Internet | Required | Broadband | For initial download | +| Internet | Required | Broadband | For initial download only | ### 1.2 Required Packages @@ -27,15 +42,11 @@ Install on Ubuntu 22.04: ```bash sudo apt update sudo apt install -y \ -
