Walkthrough

ESPLoader changes serial read, write, disconnect, reconnect, and flash-read handling. Console-port setup and cleanup are updated. Generated firmware modules are replaced for multiple ESP chip variants, and development dependencies and scripts are updated.

Changes: Serial lifecycle and flash reads

Layer / File(s)	Summary
Read-loop and stream teardown src/esp_loader.ts	The loader tracks read-loop completion, retries selected serial errors only when the readable stream changes, and adds bounded cancellation, stream teardown, and port closure.
Connection lifecycle integration src/esp_loader.ts	Reconfiguration, disconnect, console release, reconnect, and port handoff use updated shutdown handling. Each queued write acquires and releases its own writer. The classic reset path also updates its port-change result for specified ESP32-C6/C61 USB modes.
Flash-read timeout and digest handling src/esp_loader.ts	Windows non-WebUSB CP210x reads use a 1000 ms timeout. Digest lengths other than 16 bytes and digest-read failures are logged.
Console port and UI state js/script.js	Console setup reuses ports with existing streams and tolerates already-open errors. The UI clears stale connection references and resets state when replacement-port setup fails.

Generated firmware modules

Layer / File(s)	Summary
Firmware image modules js/modules/*	Generated modules add encoded firmware payloads and address metadata with named and default exports. Existing generated modules for the corresponding chip variants are removed. The ESP32-S3 module includes plugin metadata and a NAND plugin image.

Development tooling updates

Layer / File(s)	Summary
Development scripts and dependency configuration package.json, package.cli.json	The development script switches to npm-run-all2. Electron, Electron Forge, other development dependencies, and package overrides are updated.

Explanation

The title names the two main changes: a refactor of the read loop and a longer timeout for CP2102 ports on Windows. The raw summary confirms both. The 1000 ms flash-read timeout applies only to non-WebUSB Windows CP210x ports, and the read loop logic was restructured. The title does not mention the console, port handoff, dependency, or bundled ESP chip module changes, which are secondary to the main change. The wording is specific and does not use vague terms.

Close an open port after fatal stream errors.

After fatal read and write errors, both stream getters can return null while the serial port remains open. This branch returns without calling port.close(), leaving the port open and preventing a later open() on the same port. Close the port even when both streams are unavailable, while handling an already-closed port separately. (serial.spec.whatwg.org)

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Wait for reader cancellation before handing off the port.

reader.read() can finish before reader.cancel() completes. If cancellation takes longer than the console handoff delay, port.readable can still return the canceled stream, so the console reader immediately receives done. Wait for cancellation as well as loop completion before handing off the port. (serial.spec.whatwg.org)

Bound the pending-write wait during disconnect.

If writer.write() remains pending under serial backpressure, _writeChain does not settle. disconnect() then waits at Line 3578 and never reaches closeSerialPort(false, true). The port remains open, and _isReconfiguring remains true. Give graceful writes a deadline. If the deadline expires, abort the active writer and report the incomplete write. Web Serial write completion depends on the underlying write operation. (wicg.github.io)

Based on learnings, shutdown must bound background I/O waits or use cancellation-aware I/O.

Limit the minimatch v3 override to glob 7.

The root override "glob": { "minimatch": "^3.1.2" } applies to every glob version. In the lockfile, @electron/asar@4.3.0 resolves glob@13.0.7, and that glob receives minimatch@3.1.5. Its own range is ^10.2.2. The same override also changes glob@10.5.0 under archiver-utils from minimatch ^9.0.4 to minimatch@3.1.5.

On Windows, glob matches case-insensitively by default. With nocase enabled, minimatch v3 turns literal path segments, including the drive C:, into regular expressions. glob 13's Pattern.isDrive() requires that first segment to be a string matching /^[a-z]:$/i. For an absolute drive path, it returns false. The pattern is then treated as relative to the working directory, and the walk finds no matches.

@electron/asar builds its crawl pattern as src + '/**/*'. If src is an absolute Windows path, the crawl can return no files. Forge enables ASAR (asar: true), so the packaged application archive can be empty.

Scope the minimatch v3 override to glob@7 only. Glob 7 consumers (electron-installer-common, rimraf) need that range. Let glob@13 and glob@10 use the minimatch ranges they declare. Regenerate package-lock.json after the change.

Close the existing port before reselection, or keep the open-port path for classic resets.

On Web Serial, the classic branch returns true at src/esp_loader.ts:2054 for every chip on that path, not only native USB C3 and C6 devices. The branch does not close the port. Its helpers only release locks (releaseReaderWriter(), src/esp_loader.ts:3636) and send DTR/RTS signals (hardResetToFirmware(), src/esp_loader.ts:1292-1298). The console path then clears references at js/script.js:1369, requests a port, and calls openConsolePortAndInit() at js/script.js:1406. That function calls open() at js/script.js:1156.

If the original handle is still open when the chooser returns it, open() can fail with InvalidStateError. The console then fails to start and the checkbox is reset. Whether the handle stays open depends on the browser and platform, as the port-behavior learning notes. The code should not assume that it closes.

Limit the true return to chips whose port changes on this path, or close the old handle before the reselection starts. Keep the open-port console path for the other chips.

Reference

• Espressif documents RTS on USB-Serial/JTAG as a core reset, but it does not state whether the host handle closes: https://docs.espressif.com/projects/esptool/en/latest/esp32c6/esptool/advanced-options.html

Keep glob 13 on a compatible minimatch version.

The scoped glob@7 override leaves glob@13 using minimatch@11. Minimatch 11 returns Matcher objects for wildcards, but glob 13 checks for RegExp objects. (raw.githubusercontent.com)

As a result, the /**/* crawl used by @electron/asar can return no files. Forge enables ASAR packaging, so packaged applications can lack their entry point on all platforms. (raw.githubusercontent.com)

Let glob 13 use its declared minimatch 10 dependency and regenerate the lockfile.

Require both streams before reusing a port.

The reuse condition skips open() when either stream is present. If readable is null and writable is present, assignPort(newPort) runs with no read side. The console then starts no reader. Web Serial can expose this state after a fatal read error.

When the read side is missing, ESP32ToolConsole._connect() shows "Terminal disconnected", logs an error, and returns. It throws nothing, so the caller's catch does not run, and the UI remains connected with no console output.

Check both streams before the port is reused. Do not only change && to ||. The open() call would then throw "already open", and the tolerated error branch would continue with the same partial port.

Suggested fix

   } else {
+    if (!newPort.readable || !newPort.writable) {
+      throw new Error("Port streams incomplete; reselect the port");
+    }
     debugMsg("Port is already open, reusing for console");
   }

Apply the same check in the tolerated already open branch. Keep it out of the fresh-open path. The WebUSB loop after open() waits for readable to appear, so a strict check there would break the stabilization logic.

Review comment at @js/script.js at line 1157:
Update the `newPort` reuse path to require both `readable` and `writable` streams before continuing; reject an incomplete port so it cannot be assigned for console use. Apply the same validation in the tolerated “already open” branch, but keep it out of the fresh-open path so stream stabilization can complete.
