PYBCN V2 supports external 8M flash firmware [Copy link]

 

Today I tested external flash and successfully used 8M external flash as storage space. Below is the precompiled firmware, which supports double precision floating point, threading and external storage functions. If you do not need external storage, you can directly download the official PYBV10 firmware. The firmware can be upgraded via DFU or SWD. Upgrading with SWD will destroy the contents of the disk, so you need to back up the contents of the disk first.

The bin format can be converted through hex or dfu files. There are two bin files, and the corresponding addresses are:

• 08020000
• 08000000

esptool is for programming ESP8266/ESP32, not STM32. If you are not familiar with it, you can use STLink or jlink to download via SWD. DFU is actually very convenient, you need to install the ST dfudemo software first. http://www.st.com/content/st_com ... /stsw-stm32080.html
