I cannot program (flash) ADSP-CM403F processor via UART0 WSD. It unswers to the WSD in first stage of load and autobauds successfully and loads ('sending second stage kernel'), but then it tryes to eraze flash (and later if succed it would to load my hex file) and fails autobaud and does nothing more. All in one 'Start' button press.

RTS and CTS  connected and not connected were tryed.

Different 9600 to 115200 b-rates were tryed.

Board with ADSP-CM403 is custom. Althought Evaluation board with ADSP-CM408 is used and it loads ok. If it was a hardware RX TX or other error in my custom board then WSD would not connect with it at all and would not 'send second stage kernel' and autobaud succesfully with it at first stage of download.

Use of JTAG is impossiable.

ADSP-CM408 eval board programs ok.

WSD is from ADSP-CM40x_Software-Rel2.0.0

 

Picture with WSD programming proces is attached and illustrates the problem

 

What can I do with it and what messages in WSD mean?
