Talk:Forth Lesson 9

Location and Execution of OFW

OFW is stored in the 1024 KiB SPI-interface flash ROM and executes in the CPU; correct? No doubt obvious to some. The additional information would be helpful to me and others with limited background. Thanks, Peasthope 22:11, 23 October 2012 (UTC)

No, not obvious, but not relevant for Lesson 9. See Forth_Lesson_20. Summary: copies of Open Firmware are in the SPI FLASH and the internal storage as /boot/bootfw.zip, but it is the copy in SPI FLASH that is used first on power-up. On XO-1.75 and XO-4, it is copied to RAM and the CPU executes it from RAM. --Quozl 22:30, 23 October 2012 (UTC)

OK, thanks. I've added a link to Lesson 20 in case anyone else has a simialr interest. No offense if you revert or change it. Peasthope 19:06, 31 October 2012 (UTC)
