Booting VxWorks 7 with U-Boot on Cyclone V, take 2...

So I am having quite a bit of trouble trying to figure out how to get the u-boot going for VxWorks 7 on Cyclone V. I have the Cyclone V devkit BSP from WindRiver’s site and have downloaded the files from Altera for booting VxWorks.

How much of a difference between getting this done is there between VxWorks 6.9 and 7? Here are some questions or statements that I have:

Section: Build a BootROM from a VxWorks Image Project

1. Create a VxWorks Image project with the profile PROFILE_BOOTAPP.
   
   • There is no PROFILE_BOOTAPP in VxWorks 7; it is now a configuration option for the VIP called INCLUDE_BOOTAPP (or something similar).
   
   
2. Set the build spec to default_rom.
   
   • I only have a default spec, does this need to be created?
   
   
3. Build the vxworks.bin target in the project.
4. Use the vxWorks_rom.bin file in the default_rom build directory in the project.
   
   • Never mentioned again in the document. Says that vxworks.bin and vxWorks_rom.bin both need to be wrapped using ‘mkimage’ but then doesn’t detail how.
   
   

Section: Creating a Bootable Environment using SD/MMC

1. Set up the board for SD/MMC boot.
   
   • Instead of telling the reader to orient the board, could’ve just used the pin numbers
   • BSEL0: 1 [2 3]
   • BSEL1: 1 [2 3]
   • BSEL2: [1 2] 3
   • The SoC FPGA Cyclone V dev kit doesn’t look the same as the board this documentation is coming from, I don’t think.
   
   
2. Create an SD/MMC card.
   
   • Says to unzip ‘sdmmc/cv_140_fat_sdmmc.zip’ and then write the image, cv_140_fat_sdmmc.img, to the SD card using Win32 Disk Imager.
   
   
3. Load the card into your development board and power up.
   
   • Using PuTTY with the appropriate COM port and baud rate of 115200, I SEE NOTHING using the image provided. Am I doing something wrong?
   
   
4. Build the VxWorks Bootrom.
5. Add the Altera header to the VxWorks Bootrom.
   
   • In Wind River’s documentation on u-boot, it uses “-T kernel” rather than “-T firmware”. What is the difference between the two?
   • Another conflict is that there are different addresses used for the ‘-a’ and ‘-e’ options between the Wind River u-boot documentation and the Altera u-boot documentation. Confused by inconsistencies.
   • I don’t have a ‘bootrom.bin’ file; is this where I use the vxWorks.bin file?
   
   
6. Put the VxWorks bootrom on the FAT partition.
7. Boot the board with the VxWorks Bootrom.

That’s as far as I have gotten. Suggestions?
