Hello all,
I uses a custom PMC (PCI for embedded systems) board which is based on a Altera StratixII EP1S30.
This PMC is plugged on a VME board whih is based on a 405GPr processor.
The ucLinux image is generated using the ucLinux distribution provided in december 2006.
I also wrote a Linux 2.6 driver which loads in SDRAM the ucLinux image and also loads the FPGA image using FPP Mode.
When a usb-blaster cable is connected to the PMC, the uclinux boots correctly. It means that the nios2-terminal returns the print of the ucLinux kernel and the custom application added to the kernel is launched by the rc script.
Synchronisation with the driver linux ran by the 405GPr is correct.
To deploy the solution, we can not use the usb-blaster.
In this configuration, the FPGA is loaded, I think the ucLinux image is loaded into memory too, but nothing occures : I have no trace from the Linux which is ran on the VME board, which means that the ucLinux is not running....
I verified that I reset the FPGA correctly.
So what the usb-blaster could do more than my driver ???
has someone already meet this knid of behaviour ?
Thank in advance
