I try to make multiboot design. The first problem – Spartan 3ADSP not rebooting during ICAP reboot command.
SPI FLASH was successfully programmed with JTAG via FPGA. In SPI FLASH written 2 images with start addresses 0 and 0x200000 respectively. At power on first image loading in FPGA successful.
It’s strange that ICAP signals NOT visible in Chipscope. However control signal “reboot” visible. Also strange that there were no activity on SPI bus during ICAP reboot command.
