Debugging SPI slave boot on ADSP-2126x

Hi,

after successfully developing and testing an application on an ADSP-21262 with SPI slave boot from an ATMega644  i redesigned the board and got stuck when booting. The (as i hope) only change was switching the compiled code from ADSP-21262 to ADSP-21261. The 21261-code works fine on the old hardware with the ADSP-21262.

To overcome this problem i have the following question:

Is it true that the RESETOUT only goes high after a reset when the processors has a sane clock and the 4096 CLKIN cycles have finished? Is this a valid indication for a working processor core?

Regards, Kurt
