Flashing over Uart
Hello,
Can somebody help me, how i can flashing my firmware over UART without bootwizard.
I want to write an program in Delphi.
The configuration for the UART is:
Parity : none;
Databits : 8
Stopbits : 1
Baudrate : 115 KB
For checking that the NETX is in Bootmode i must send:
"VERS"+#13+"DUMP 20000 2"
But then, I dont know ?
I have already a own Flashingprogram over USB.

Hi Rainer,
3 simple steps to success...
1) download your flasher and the data file (to be flashed) from pc to netx
2) execute the flasher
3) read the status of the flash operation
You already discovered the "VERS" command. The "LOAD" command downloads code from pc to netx. The syntax is:
LOAD
Please take a look at this source for an example implementation. The "write_data" function starts in line 931:

The "CALL" command executes code in the netx memory:
CALL
The "parameter_r0" is passed in register r0 to the routine, i.e. it has the prototype "void my_routine(unsigned long parameter_r0)". An example call function starts in line 1069.
