3 Firmware upgrade and version
upgrade
IAP is a software function module of the system, that is, in
application programming, that means upgrade the single chip
computer program online. This function uses the upper computer
to burn the new version bin file to the single chip computer
(including the central control board, the motor drive board, etc.)
when the program is running. The premise is that the single chip
computer’s bin file, which will be burned, needs to be named
according to the requirements of the upper computer,and places
it under the“/sdcard/firmware/”path of the upper computer. And
then the bin file can be upgraded online through the command at
the terminal.
3.1 Firmware upgrade
Before the firmware upgrade, it is necessary to test the data
communication between the upper computer and each lower
computer to check whether the communication is normal. Use
the command to test in the shell terminal.
