Is the VC-02 reprogrammable

[aaronloo]

I have been testing these units and I have flashed the programmable firmware a single time, but after a power reset they appear to not be reprogrammable. I would like to verify before continuing development.

------Question for VC-02-KIT Please Put your question below------

Hello,

I am checking on this. Will post when I have an answer for you.

This excerpt was taken from the spec sheet:

VC-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.

If you read bullet point 2 the firmware must have a specific name. Nothing in the spec sheet says the part is OTP, which should be specified, otherwise it should be reprogrammable.

I’ll keep looking.

Here is the response from the supplier – this should help them with their inquiry.
