Smart Home Automation Forum

Hi,  please can you link to a guide that describes how to flash KC868-A16 using idf.py or similar Linux CLI tool ?

I think reading the forum that the source for "firmware 2.1.9" is not available - please advise if I got this wrong.

thanks!

I do not have a windows computer, so I cannot use the windows tool.  I can program the board using the esp32 tools (https://docs.espressif.com/projects/esp-...setup.html)

However, these tools are expecting a build environment and don't describe how to flash a single file, without the environment.

What is the command you recommend to "use command line to download firmware" ?

thanks

I built an environment, and I can program the board with:

esptool.py --chip esp32 -p /dev/ttyUSB0 -b 460800 --before=default_reset --after=hard_reset write_flash --flash_mode dio --flash_freq 40m --flash_size 2MB 0x1000 bootloader/bootloader.bin 0x10000 hello_world.bin 0x8000 partition_table/partition-table.bin

I (316) main_task: Calling app_main()

Hello world!
This is esp32 chip with 2 CPU core(s), WiFi/BTBLE, silicon revision v3.0, 2MB external flash

To flash KCS_KC868_A16_V2.1.9.bin - what are the correct parameters to use ?

I am wondering if the bin file provided includes bootloader.bin, application.bin and partition_table.bin in a single file, but do I use 0x1000 offset ?

thanks

without any other files, the BIN file is ALL IN ONE. download by address 0x0
