# LocalHarvest — machine-local primary documents copied into the archive
## Obtained
| file | title | version / date | source URL | bytes | pages | sha256 (first 16) | relevance |
|---|---|---|---|---|---|---|---|
| espressif-silicon/esp32-p4_technical-reference-manual_en_pre-release-v0.7.pdf | ESP32-P4 Technical Reference Manual | Pre-release v0.7, PDF built 2026-08-20 | local copy: /home/goblin/00-projects/0x4200.cafe/01-esp32p4-m3/docs/esp32-p4_technical_reference_manual_en.pdf (orig. docs.espressif.com) | 23537234 | 3701 | 622fe9625d19cf00 | ch.2 High-Performance CPU (CSRs), ch.4 Processor Instruction Extensions (PIE), ch.5 Low-Power CPU, ch.9 System and Memory (memory map/cache), ch.13 Chip Boot Control, ch.14 Interrupt Matrix, ch.17 System Timer, ch.18 Timer Group, ch.19 Watchdog Timers, ch.3 RISC-V Trace Encoder |
| espressif-silicon/esp32-p4_datasheet_en_pre-release-v0.7.pdf | ESP32-P4 Series Datasheet | Pre-release v0.7, PDF built 2026-07-14 | local copy: /home/goblin/00-projects/0x4200.cafe/01-esp32p4-m3/docs/esp32-p4_datasheet_en.pdf (orig. docs.espressif.com) | 1576185 | 102 | fb4f3e91cc2ac519 | Product Overview (HP dual-core RISC-V + LP core), §1 pin/package, §4.1.4.6 Low-Power Management, in-package PSRAM (16/32 MB) sizing for flash/PSRAM mapping |
Both were verified with `file` (PDF document, version 1.5), `pdfinfo` (page counts above) and `pdftotext -f 1 -l 3` (title + "Pre-release v0.7" text). Destination directory was empty at copy time, so neither is a duplicate; EspSilicon was notified of the names and sha256s over hub so any newer upstream revision lands under its own rev-suffixed name rather than overwriting these.
## Not obtained
| wanted | why not | best known pointer |
|---|---|---|
| RISC-V unprivileged/privileged/debug/psABI specs | no RISC-V specification PDF exists anywhere on this machine (bounded `find -maxdepth 6 -iname '*.pdf'` over 0x4200.cafe, ~/esp, ~/.espressif, ~/Downloads, ~/05-genizah; ~/Documents does not exist) | RiscvSpecs agent, upstream github.com/riscv |
| ESP-IDF / esptool / OpenOCD manuals as PDF | not present locally; the ESP-IDF checkout ships only reStructuredText sources, and the only PDFs under ~/esp/esp-idf are a Unity assertions cheat sheet and a logo asset | EspSoftware agent, docs.espressif.com PDF builds |
| ESP32-P4 errata / ECO sheet | no local copy | EspSilicon agent |
## Belongs elsewhere
- ESP32-P4 TRM/datasheet at a revision newer than Pre-release v0.7 — `espressif-silicon/`, owned by EspSilicon (upstream fetch).
- ESP-IDF Programming Guide, esptool, OpenOCD-ESP32 manuals — `espressif-software/`, owned by EspSoftware.
- RISC-V unprivileged/privileged/debug specs and psABI — `riscv-isa/`, owned by RiscvSpecs.
- PIE / Xesppie custom-instruction and LP-core documentation extracted upstream — `espressif-custom-isa/`, owned by EspCustomIsa.

## Local non-document sources
Code/reference material, authoritative but not documents — must NOT be copied into the archive:
- /home/goblin/esp/esp-idf — ESP-IDF checkout, `git describe` = `v6.0.2` (HEAD 7101770d); reference implementation of startup, image format, cache/MMU setup, interrupt allocation.
- /home/goblin/esp/esp-idf/components/esp_rom/esp32p4/ld/esp32p4.rom.ld — mask-ROM symbol addresses for the HP core; sibling files `esp32p4.rom.api.ld`, `esp32p4.rom.eco5*.ld` (ECO5 silicon variants), `esp32p4.rom.systimer.ld`, `esp32p4.rom.version.ld`, and `esp32p4lp.rom*.ld` for the LP core.
- /home/goblin/.espressif/tools/esp-rom-elfs/20241011/esp32p4_rev0_rom.elf — full boot-ROM ELF with symbols; disassemble for ROM loader protocol and entry points.
- /home/goblin/esp/esp-idf/components/soc/esp32p4/register/hw_ver1/soc/ — the `hw_ver1` (pre-v3 silicon) register headers this project's revision needs; includes `cache_reg.h`, `assist_debug_reg.h`, `efuse_reg.h`, and the matching `*_struct.h` bitfield definitions.
- /home/goblin/.espressif/tools/riscv32-esp-elf/esp-15.2.0_20251204/ — installed toolchain, `riscv32-esp-elf-gcc (crosstool-NG esp-15.2.0_20251204) 15.2.0`; ground truth for the arch string and psABI behaviour. Note: this compiler *rejects* `xesppie` ("starts with 'x' but is unsupported non-standard extension"); the real rev<v3 string is `-march=rv32imafc_zicsr_zifencei_zaamo_zalrsc_xesploop_xespv2p1 -mabi=ilp32f` — see `manifests/EspCustomIsa.md`.
