JN518x: any open source script for UART ISP flash programming?

usaygo · ‎04-03-2022

Hello,

I'm looking for ISP programmer (via UART) script as an alternative of DK6Programmer. Is there any recommendation? It's okay if it's not supported JN518x fully, but close one. I'm thinking of using Raspberry PI or other UNIX like platform.

@Ricardo_Zamora any updates on the sources for DK6Programmer. I need to compile it on an OpenWrt based board so we can program the JN589 on board

Hello,

Unfortunately I did not get any resouces and finally I did it myself (sorry, it can't be disclosed as open source...).

I put a memo when I analyze its protocol. The packet definition can be found from JN518x datasheet (tailing four bytes are CRC32 checksum).
