from struct import * t = (2022, 2) test=pack("<%di" % len(t), *t) print (test) output: b'\b'\xe6\x07\x00\x00\x02\x00\x00\x00'\x07\x00\x00\x02\x00\x00\x00' ------------ Well, as you may know 'utf-8' codec can't decode byte 'xe6'. However, micropython only supports uft-8. I mean I need to run 'test.de...

I just want to tell you guys, I just try the toolchain from esp-open-sdk, version=4.8.x , now it's working for me Hi kevinscorpionfox, I would like to use ESP8266_RTOS_SDK. Can you be more specific what you have done exactly. You mentioned some problems I'm totally confused now. SOS. Thanks, hcet14...

been tested. If you want to compile esp32, get your toolchain from there:

I just want to tell you guys, I just try the toolchain from esp-open-sdk, version=4.8.x , now it's working for me, I will try to compile esp32 with the latest toolchain and the older one, later.

My system is ubuntu 20.1 since I think esp-open-sdk is old, I've got the latest toolchain from here. https://github.com/espressif/ESP8266_RTOS_SDK. And I have done the path as well. $ xtensa-lx106-elf-gcc --version xtensa-lx106-elf-gcc (crosstool-NG esp-2020r3-49-gd5524c1) 8.4.0 now I think toolchai...

Emmm, I'm not gonna encrypt a text file, but thanks anyway.

Another option is to use an esp32 based module. First you can compile the py file as frozen code and append it to the firmware binary. If you enable secure boot + flash encryption, you can ensure that the flash content cannot be cloned as the keys are stored inside fuses on the esp32. "Another opti...

There is a way to make .uf2 run on exactly one (Raspberry Pico) by encrypting the image with Pico's unique flash ID ... https://www.raspberrypi.org/forums/viewtopic.php?f=146&t=306449&p=1862153#p1862153 The .uf2 image can contain MicroPython code builtin as others have described. Honestly to say, R...

Unfortunately, even contracts are not generally enforceable when it comes to Chinese companies. Cross jurisdictional enforcement and a burden of proof are very, very expensive things. You may need to reconsider your development board. One that natively supports encrypting firmware through the use o...

Not on any of the MicroPython systems I've used. Compiling to mpy will keep out the casual code browser, but the whole filesystem can always be cloned. If one or other of you aren't being paid, that sounds like you don't have a contract in place. I'd fix that first. Oh mpy files, sounds a good idea...
