DualCore App doesnt boot from SPI if ext.RAM is used

Hi !

We have our own BF607 based board and use either SPI or RSI to boot the processor.

Without using external DDR-RAM no problem to boot a dualCore app from both boot-interfaces.


Now we have written code that request data in ext.RAM and also some functions are located in ext.RAM

Therefor a special init file was adapted from the given example to fullfill our RAM-spec.

But loader/init code is executed after flashing SPI&booting and the the DSP hangs.

No idea where and how to debug this. loading LDR file seems to be working until the SRAM section is reached???


thanks for support
