VC-01/02-Kit has two methods for firmware upgrade , JTAG debugger program and serial port program.
JJTAG debugger uses VC series dedicated JTAG debugger, Jlink series debugger are not supported,The firmware file name being used is:uni_app_release.bin
Serial port program is USB program mode (module requires external TTL to USB module access to TX1 and RX1), the firmware file name being used must be uni_app_release_update.bin (cannot rename for ‘uni_app_release.bin’), make sure to use the “build.sh update” instruction to compile.
