JN518x flash programming protocol

[usaygo]

Hello,

Is there any document of flash programming protocol between PC and JN5189?

Previously the document "JN51xx bootloader operation" does explain it. Now JN5189 seems to have very different protocol.

[usaygo]

Just for reference, I picked up the simpler commands sequence to write data onto FLASH of JN518X.

//Seigo

Command Bytes Sequence:
0000094E00A709AE19
^1^^^2^3^4^^^^^^^5
1: always zero
2: size of the sequence (including all bytes, bigendian)
3: command id (0x4E=Open ISP)
   or response id
4: command parameters (depending on commands)
   or response parameters (the first byte always its command status, success or error code)
5: CRC32 (from 1: to 4:)

=== 
Firstly set ISP pin as LO and RESET module, 
The connect UART port as 115200bps 8N1.
