Loading Compressed vxWorks Images

Getting the vxWorks bootloader to load a compressed vxWorks image from flash is a piece of cake!

  1. Add a rule to the makefile to create vxWorks.Z by doing elfToBin and deflate.
  2. Change bootConfig.c. Add some code that opens, reads, and inflates the compressed file in tffsLoad(). You'll want to inflate to RAM_LOW_ADRS, and pass this address back through pEntry. I check to make sure the file has a ".Z" -- this way you can still load an uncompressed file.
  3. That's all there are for changes! Rebuild, reflash your bootrom, download the compressed image and let 'er rip.
