ESP32: Seems to completely stall the ESP32 after a few seconds #108

Closed probonopd closed 5 years ago

probonopd commented 5 years ago

Testers and contributors with ESP32 devices needed.

With ESP32-PICO-KIT module:

After flashing the ESP32, the web interface and telnet are working for a very short period of time, until everything freezes and cannot be reactivated anymore without flashing again. Not even power cycling helps.

With no printer connected:

root@host:/home/me# telnet 192.168.0.16
Trying 192.168.0.16...
Connected to 192.168.0.16.
Escape character is '^]'.
Connecting at 115200
>M115
Connecting at 250000
>M115
Connecting at 250000
>M115

(Stalling here. Does not continue. ESP32 no longer reachable over the web. Power cycling the ESP32 does NOT seem to help? But reflashing does)

What is ph⸮ph⸮⸮⸮?

probonopd commented 5 years ago

Second module (ESP-WROOM-32):

rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
flash read err, 1000
Falling back to built-in command interpreter.
OK

But then the sketch starts, says

me@host:~$ telnet 192.168.0.17
Trying 192.168.0.17...
Connected to 192.168.0.17.

then stalls. Resetting the module does work here, the sketch starts again.

This one, with maximum verbosity on, shows on the serial console:

So this one dies with I⸮E⸮...

Next try:

M115
T#T⸮⸮
probonopd commented 5 years ago

Next try:

M115
M115
T⸮T⸮

So, some randomness.

probonopd commented 5 years ago

When I replace detectPrinter() with

bool detectPrinter() {
  return false;
}

then it does not stall the module and the web interface stays responsive for more than just a couple of seconds.

probonopd commented 5 years ago

The random characters above are "M115" sent at different baud rates. Looks like the ESP32 crashes when trying 500000.

probonopd commented 5 years ago

With const uint32_t serialBauds[] = { 115200, 250000, 57600 }; we do not crash the ESP32.
