Er... as a matter of fact I did read that very thread before I built everything. As far as my understanding goes, I followed all the steps described there, this is precisely why I mentioned that I erased the flash and performed the 'make axtls' command as instructed by the post. I will continue to l...

I tried to compile the firmware (had not done so since the official release). The firmware compiled but I cannot connect to webrepl anymore. I am wondering what I could have done wrong. When I try to connect to the regular webrepl, I get a "access denied" message after entering the password and if I...

According to the tutorial, default password is "micropython"

Dear Paul,
Thank you for the explanation on the two heaps being separated.
I will try to compile the master and see if the increase in RAM is enough for me to load my modules.

@Deshipu : and now I understand better why const() does not really help here, thank you.

I see,
So that might explain why I can paste the code directly in the REPL but it fails to import in a module if it cannot benefit from the const() optimization.

I tried to split my module like Pythoncoder suggested and stored all the static values in a separate module: MAX_LEN = const(16) PCD_IDLE = const(0x00) PCD_AUTHENT = const(0x0E) PCD_RECEIVE = const(0x08) PCD_TRANSMIT = const(0x04) PCD_TRANSCEIVE = const(0x0C) PCD_RESETPHASE = const(0x0F) PCD_CALCCRC...

OK so I removed webrepl from boot.py but I still do not have enough memory to load my module.
I guess I will simply have to shelve the whole project until I the frozen bytecode becomes usable on the ESP.

Best regards,

Llwy

Thank you Deshipu and Pythoncoder. I had kind of hoped that it was some sort of bug instead of a real memory issue. I do not have much experience in low-memory programming so there is possibly room for improvement. I will try with the webrepl deactivated and cross my fingers for it to be sufficient....

Hello, I am working on a module for the MFRC522 RFID reader. The module size is 11KB I managed to copy the module on the micropython filesystem with the help of webrepl_cli.py. When I try to import the module through the UART REPL, I get the following error: MemoryError: memory allocation failed, al...

Hello,

For what it's worth, I agree with Dave's comment and I would personally find it very useful to have a user supplied dictionary or list.
This could be something like machine.SetConvenienceMapping(mydictionary)

Not a vital feature but indeed something very convenient.
