Hi, I have been asked to look at a legacy Tornado 1 system which boots from a DiskOnChip to see if this can be changed to boot from a compact flash disk. The compact flash is on the primary channel of the *second* IDE controller. I dont understand the boot line: "#define DEFAULT_BOOT_LINE "ide=0,0(0,0)host: ..........." Where is this documented? What are the 0,0's? I presume I have...

Hello, recently I wrote a virtual network card driver of vxworks and suffered some questions . The driver works as follows: When receiving the data, the driver receives MAC data frames from FPGA and deals with them . Then put some MAC frames into TCP/IP protocol stack of vxorks . And receive the datas by socket program in application level. When sending the data, useing socke...

Hi, I am implementing firewire interface with MPC8347 Microcontroller using VxWorks RTOS. I am using TI's TSB43AB23 firewire OHCI link/PHY layer controller which is connected to MPC8347 using PCI Interface. Both TSB43Ab23 and MPC8347 are configured as PCI master and only these 2 devices are present on PCI bus. When I connect a Firewire Simulator/Analyzer to TSB43Ab23 I am able to receive SelfI...

I'm having great difficulty getting a 16550 UART to transmit parity/2 stop bits. I'm using vxWorks6.4, Workbench2.6 tools for an MVME5100 (74xx processor board). I get no errors returned on the ioctl() calls and the options read back equal the options set--but the UART is not transmitting parity bit and not transmitting the 2nd stop bit (in other words, the only change from the default values tha...

Hello, I needed to get ideas on how to simulate a FIFO interface on the PCI interface. I have a SBC w/ vxWorks and a Communication board in a cPCI chassis. The SBC runs an application that feeds data through the PCI interface to a FIFO on the Comm board. The Comm board has a number of control and status registers and receives data through a single 32-bit memory mapped address (that is the in...
