Minor change to Makefile in micropython/port/w60x directory.
To avoid a wrong output by the function w600.version() due to 2M Flash size setting it is sufficient to change the Makefile line 347 from:

CFLAG += -DW60X_USE_2M_FLASH=1
to:

CFLAG += -DW60X_USE_1M_FLASH=1

as clearly shown in the attached picture

w600.version() wrong output

That's OK. But I do not use the 2M flash setting in my build. Instead I modified the file link_w600_1m.ld allowing more space for the firmware.

Hi Roberthh,

I successfully compiled your most recent 10-23-2020 w60x micropython for the w600-pico and have been successfully compiling and using recent versions with much success. Specifically I am using it for IoT with mqtt; this works fine.

Most recently, I'm getting an ImportError: no module named 'ussl' when I import urequests and try to use it:



Do you have any suggestions?

Thanks.

For ussl you have to set in Makefile:

MICROPY_SSL_MBEDTLS = 1

This is normally only enabled for 2Mbyte flash devices, which are hard to get. Setting the flash as above, the code area may overflow. Then you have to increase it in tools/link_w600_1m.ld, line 10.
