 | | Firmdl3 updated
|
|
Following a discussion on lugnet.robotics on firmware versions and firmware checksumming, I realized firmdl3 was broken for the latest firmware files (firm0325.lgo and firm0328.lgo). The problem was these files were too big. I have modified firmdl3 (...) (24 years ago, 16-Dec-00, to lugnet.robotics.rcx.legos)

(...) Actually, the kernel can hit 21-22K (depending on the compile-time options.) My current legOS.srec sits at 21232 bytes. So, I'm going to do the update. Luis (sort of wishing that Markus had not made so many little changes to firmdl) ---...--- (...) (24 years ago, 20-Dec-00, to lugnet.robotics.rcx.legos)

(...) Isn't the actual size of the kernal about half the .srec size? That file contains ascii codes for for hex bytes, a pair of characters would be one byte. Rossz (24 years ago, 20-Dec-00, to lugnet.robotics.rcx.legos)

(...) I wasn't completely sure how much extra data there was in there; I knew it was larger but didn't realize by how much. Regardless, I'll merge in the changes anyway, since I don't want our tree to diverge too much from the One True tree. Luis (...) (24 years ago, 20-Dec-00, to lugnet.robotics.rcx.legos)

(...) So my 18k kernel actually only takes 9k of RCX memory? Suddenly my apparent out-of-memory errors make a lot less sense.... (24 years ago, 20-Dec-00, to lugnet.robotics.rcx.legos)

(...) Here's how to determine size given a .srec file: 1) Look at the last S1 line in the s-record file. An example from firm0328.lgo: S113E1606F... 2) Look at characters 4-8 (start counting with 0): S113E1606F... ^^^^ This is the starting address (...)

(...) My legOS.srec file, which is compiled with all the default settings, is exactly 21000 bytes long. The calculated size is 8144. Which is sort of in the ballpark of half the file size (if we use a very big ballpark). The proper estimate is (...) (24 years ago, 20-Dec-00, to lugnet.robotics.rcx.legos)
