Hi,

I use stm32 to programe IWR1642 image by uart. Here I meet some problems;

According to the SWRA563 page 12,

A、 Flashing Sequence:

HOST IWR1642

1. UART Break ACK

2. Get Version ACK

3. Get Status status

4. Open Cmd (cmd=0x21,FileType META IMG1(4)) ACK

5. Erase Flash ACK (long time)

6. Write Flash(cmd=0x24) nothing ???

How to write ?

Hi,

Are you flashing using uniflash?
Can you send a screenshot of the interface and console output?

no, i am using an external host--stm32. According to the "SWRA563", we transfer commands to IWR1642. Some of the commands can be replied,like "Open command","Erase command" etc. But when I send the "Writ command", the IWR1642 doesn't reply. Is the Sequence error or anythin else?

Hi,

Can you please provide some more details about the setup. Are you using an STM32 as the USB to UART interface or as a host MCU?
