Hi, Thanks to some help from this group, I managed to build the IXP1200 applications for Vera. I also built and ran the Hello World test program. Now I have a problem running the IPmm and PktGen applications. When I invoke 'sgo ipmm.srec', the output on the board's serial port stops abruptly. Here is the output. =============================== Jumping to: 0xC1002000 bss_start = 0xC10121A8 bss_end = 0xC1012A40 (length) = 0x00000898 Sbrk_heap_ptr_ = 0xC1013000 Sbrk_heap_end_ = 0xC1CF8000 (length) = 0x00CE5000 (13204 Kbytes) Enabling MMU MMU enabled Calling sram_init() Calling scratch_init() Calling PCI_mapout_init() PCI_mapout_init: PCI_dram_siz = 0x02000000 PCI_mapout_init: PCI_dram_bar = 0xF6000000 Calling my_main() Starting uEngines and control program. --- Control_SystemStart --- Contr ========================== This happens irrespective of if I build the microcode with or without VRP. The LED displays 0x25. The same happens with the application PktGen. What have I done wrong here? Thanks, Magesh
