Re: Reviving the Vera project!
The problem with that is that you get seemingly random delays when working with files. We'll have to choose if we want seemingly random delays or a generally slow file system or leaving garbage collecting to the user or have a very inefficient file system... Edit: also, it wouldn't have wear levelli...

Re: Reviving the Vera project!
I'm kind of interested in the file system implementation. In Vera, will there only be a filesystem in flash memory, and all ram will considered volatile? Or will there also be a ram filesystem? I'm not sure we agreed on the latter, but yes, the main file system should be entirely in flash, not usin...

Good to hear! :) http://vera.timendus.com/ svn://timendus.student.utwente.nl/vera SVN user/pass: vera/calcloversplace If you want an account on the wiki/to be added to the mailinglist, drop me a line. Like I said; we really need file storage and TI-OS compatible link routines. Any help in those dire...

Re: Reviving the Vera project!
Hey dude :) I've been playing with it a bit just a month or two ago, but haven't made much progress. I've made an include file for "Vera applications" and written a few small apps, but the problem is that the binaries still need to be compiled into the kernel, because we don't have linking...

Re: I think I should finish bubble bobble
Hello all, good to be back :) I'm not sure about the link assist, seeing that all I can test with are old TI83s and PTI. However, I tried to use the information on the wikiti as much as possible, and I thought I'd added a few port writes to disable the link assist. Looking through the code I can't s...

I see what you did now... I find it hard to compare the two approaches to determine which one would be better... I think I'll stick to my implementation for now, for the sake of simplicity and the fact that it is more extensively documented. But I'll keep an eye on yours in case my use case gets mor...

I thought that's how you implemented it. Shouldn't it be 5 bytes overhead then? Anyway, I don't agree with your stack idea. How then would you know where to allocate the next block after a few frees? If you don't actually register any frees it'll just keep growing untill you run out of memory, would...

Well, yes, but how would you implement a stack-ish thing? ;) Probably in much the same way, and this has the added benefit that you don't have to free your memory in the exact opposite order if your application allocates multiple blocks. Also, like I said, I hope to implement a sort of application-s...

They are, but I don't really see that as a problem (for now). The use case will probably be very simple anyway: Run application: - Allocate memory for application - Copy and run it - Application allocates memory for internal data structures (usually one block) - Application runs - Application frees ...

I've written a linked list kinda-first-fit memory allocation routine for Vera. It returns a pointer to free memory of the requested size after $C000 (non-executable). There's a three byte node overhead. Here's my code, let me know what you think ;) Note that it still has two TODOs: checking if there...
