Invalid signature on Mega

[djmuerteitm]

Hi!

I have a Controllino Mega, and im trying to enter configuration menu to set and store my own parameters after sucessfully sketch upload, but when I short RXD2 to ground, i receive "invalid signature". No errors during compilation or upload.

I've tried to modify settings to mine in configuration file (IP, broker, etc), but after compile and upload (no errors) i cant reach Controllino on Network (ping not responding). It seems like settings won't be stored by this way, maybe?

How can i fix it or skip signature device verification? Other sketches uploaded with ethernet integration works fine, Controllino works well for sure.

Thanks in advance!!

Hi,

RXD2 to ground puts controllino in a totally static mode without any network.

"Invalid signature" message is not an error, it just means that the configuration stored in EEPROM is either empty (like in your case) or incompatible (e.g. from a previous version). You can run controllino normally with this code, and once it is running go to configuration menu, set it all and reboot.

If possible please attach a log from the terminal, I will look into this.

avrdude done. Thank you._

**I have been upload your sketch with no modifications.
And output for serial monitor:
23:25:35.984 -> Fallback logic
(when short RXD2 and ground):
23:25:41.349 -> Loading configuration...signature invalid!!!

Board information displayed on IDE:
BN: Arduino/Genuino Mega or Mega 2560
VID: 2341
PID: 0042
SN: 5563231373835161E002

Must be caused by wrong bootloader?

All libraries and boards of IDE are full updated. Running on Ubuntu 20.04, IDE 1.8.13.

Thanks in advance.**

@djmuerteitm Did you change the #define TRACE_LEVEL_DEBUG 1 ? Because you should be seeing the other debug messages such as the one from this code:
DEBUG_PRINT("Initializing PLC");

When the configuration is invalid, the controllino is in non-initialized state. Have you tried sending enter to the serial console? You should get the message To enter configuration mode press C

I will try to prepare better instructions in readme.md so that it's clearer how to get it started. I agree it is a bit confusing, I left the process from the old project I forked and it's not very obvious what should be done.

[djmuerteitm]

I will try send Enter and i tell you. Thanks :)

Hi again.

I sent enter using serial session, as you told me, throug Putty and i can reach config menu, but i cant set the parameters correctly. I try to set MAC using ( ), without it, on caps... but on reboot controllino and enter again on config menu, the params stored are like this...

1: Enter MAC => (0:0:2:a:0:3)
2: Enter IP => (192.000.008.001)
3: MQTT Server IP => (192.136.000.008)

Valid MAC is 90:a2:da:00:53:55
Ips are 192.168.1.70 for controllino and .50 for mqtt broker, but i cant set it right.

Trying set parameters on the sketch, but same results and no response to ping.

Any ideas? Thanks in advance :)

[djmuerteitm]

Update:
I tryed uploading another sketch, and upload yours again, with configured params on it, and it works.
But if I reboot controllino without RXD2 and GND shorted, it seems like settings are not loaded again (no ping). I need to short them to make it work again.

Reboot without short pins = not working and no ping
Reboot momentary shorted or still shorted = works.

Needs to still shorted?
