1 year ago In fact this is little more critical than a feature request. After flashing with the example, the device always remains in download mode.
try {
const loader = new EspLoader(this.port, { debug: true, logger: console });
options.logger.log('connecting...');
await loader.connect();
try {
options.logger.log('connected');
options.logger.log('writing device partitions');
const chipName = await loader.chipName();
const macAddr = await loader.macAddr();
options.logger.log(`chipname: ${chipName}, mac address: ${macAddr}`);
await loader.loadStub();
await loader.setBaudRate(115200, 921600);
if (options.erase) {
options.logger.log('erasing device flash...');
await loader.eraseFlash();
options.logger.log('successfully erased device flash');
}
await partitions.reduce(async (lastFlash, partition) => {
await lastFlash;
options.logger.log(`\nWriting partition: ${partition.name}`);
await loader.flashData(partition.data, partition.offset, (idx, cnt) => {
if (options.progressCallback) {
options.progressCallback(partition.name, idx, cnt);
}
});
await new Promise((resolve) => { setTimeout(resolve, 100); });
}, Promise.resolve());
// Has no efect:
await loader.flashFinish(true);
options.logger.log('successfully written device partitions');
options.logger.log('flashing succeeded');
} finally {
await loader.disconnect();
}
} finally {
await this.port.close();
}

Thanks for this awesome library!!!
In my case, sometimes the device gets stucked in download mode. In this device I have to press a button to put IO12 low in order the device to be flashed (MTDI(IO12) in ttgo lora). So if the download has started, the device gets in download mode, but if the button is not pressed, the device keeps in download mode. The previous firmware is there and working but the device is stuck in download mode. The only way to reboot the device is with hardware reset button or disconnecting the battery.
Would be really great to have a method to reset the device when it is in waiting for download.
I've tried to manually send a flash finish with no success, it throws a timeout:
The output logs I get are the following ones, it seems to be communicating with the device:
On the other side, would be also really awesome to have reader data available, so we could monitor devices on the browser. Right now I have my own monitor and when I want to flash, I stop my read loop, leaving port opened and then I connect to EspLoader. This way I could delegate all the work to the library, monitoring and flashing...
