I came across a few times with the same error: "No code in Flash" when I toggle power of ESP-12. This time root of the problem is the code size. If I remove some part of application code, it loads and executes well, and it starts on power toggle. If I re-add that part of (unimportant) code, my application works OK, but it doesn't start when power is toggled. If
load()function is executed, it prints "No code in Flash":_____ _ | __|___ ___ ___ _ _|_|___ ___ | __|_ -| . | _| | | | | . | |_____|___| _|_| |___|_|_|_|___| |_| http://espruino.com 1v86.171 Copyright 2016 G.Williams Espruino is Open Source.

@tve
require("ESP8266").logDebug(false)solved the issue. Thank you... -
I'm using
Serial2.TXfor a specific purpose and withoutRXpin, it satisfies my needs. As of now, I can useSerial2by sending my datanaber(meanshello) as normal.With a fixed interval,
Wifimodule sends some garbage toSerial2, so what I could capture is as follows:ernabernabernabernabernabernabernabernaber849614> Wifi event: probe request from station 74:f0:6d:09:91:54, rssi = -58 849644> Wifi event: probe request from station 74:f0:6d:09:91:54, rssi = -61 nabernabernabernaber850186> Wifi event: probe request from station 00:26:ab:e8:43:82, rssi = -61 850188> Wifi event: probe request from station 00:26:ab:e8:43:82, rssi = -62 850256> Wifi event: probe request from station 00:26:ab:e8:43:82, rssi = -62 850298> Wifi event: probe request from station 00:26:ab:e8:43:82, rssi = -62How can I make these logs stopped?

As the latest build (1v86.171) uses
boot_v1.4...., the old flashing options work as expected. -
I figured out the problem: It's all about my bundling script that uses uglifyjs where it drops
lastAddrvariable in FlashEEPROM by claiming "it's declared but not used". I changed appropriate flag of uglifyjs and all went ok. -

@Wilberforce I think that library will work for me, let me try it out.
@tve Actually we don't have to stream in a non-stop manner, we can take a breath for WDT in the process.
@allObjects you hit the nail on the head... We were considering putting another MCU (eg. STM32F030) for this kind of stuff...

I need to dump a file content (while making some little changes on the fly) from ESP12 to its serial console. Filesize is about 140 KB (an image file), so the content shouldn't be copied into the RAM.
FlashEEPROM.readMem()still (as of 1v86.66) seems to cause reset.Is there any workaround or something?
-
If I use FlashEEPROM as is (without a parameter), any attempt to write something into EEprom causes
load()command to respond withNo code in Flasherror. I'm using 1v86.66 (compiled by myself)process.env.GIT_COMMIT ="a82d081a244d09706c3c885add25945008a08b6d" -
How can we calculate the
0x076000innew (require("FlashEEPROM"))(0x076000);? It isn't something fixed, right?Is it something a little bit more than Espruino size?

You mean by
this.socket.close()? It's not working sinceUncaught Error: Function "close" not found!.Here is my current workaround: Before calling
net.socket(), I delete all members ofMyClass.socketmanually:... for (var member in this.socket) delete this.socket[member]; this.socket = net.connect(...Edit:
This workaround seemed to free some memory but obviously does not prevent old sockets from connecting server when possible, hence consuming memory. (I don't understand what is going on...)
-
Hi everybody,
Do we have an option to cleanup socket object without a hard reset?
I'm connecting to a server with a tricky path and I need to try to reconnect with
net.connecton any error. But this process consumes memory on every attempt.Minimal pseudo-like code is as follows:
function MyClass(....){ this.socket = null } MyClass.prototype.connect = function (){ this.socket = net.connect(....) } var my = new MyClass(..) my.connect() my.connect() my.connect() -
Then we have only a separate hardware watchdog IC option for our own purposes (separate from Espruino's main loop)?
-
There is no console, so I can not
reset(). I am able toerase flashand re-flash the firmware, but it didn't help.It may sound weird: although I can flash/re-flash and use other ESP's, I am not able to do so with this ESP as I told; but my colleague is able to flash it. That means it's absolutely releated with my computer (but how come I could flash/re-flash/load-app with the other ESP's?)
-
Yes, I would use it on ESP8266. You don't mean it's not implemented by hardware, do you?
-
...which means we have to check
if sckt isnt undefined and conn is truein order to ensure that we have a working connection between the server, right? -
I didn't find the settings in order to automatically subscribe the threads created by myself automatically. Where is it? Following settings are not working for me:
