Hi, We are porting ECOS for our Virtex-4 board. Unfortunately I have some doubts about the processor variant 'CYGHWR_HAL_POWERPC_PPC4XX_405' we choose. This variant assumes that for example the following peripherals are present: interrupt controller, I2C controller etc. Most of these peripherals we will also implement as IP-Core in the Virtex-4 FPGA. Unfortunately most of the peripheral registers doesn't map on the registers defined in file var_regs.h.
Therefore I think it would be more logical to define a new processor variant 'CYGHWR_HAL_POWERPC_PPC4XX_405D5' (the Virtex embedded PowerPC 405D5) and move the necessary implementation for the interrupt controller, i2c controller etc to the platform submodule. Please, could somebody advice me on the above mentioned proposal. Thanks & Regards, Herman Garritsen
