When I first read what you just wrote, my thought was what the heck does "information-safer" mean, but then I see further below that you are worrying about intentional backdoors and the like in the code. Because TI is not Qualcomm and never was anything like QC, I personally consider the possibility of intentional backdoors or spying logic in their code to be extremely unlikely, and I choose not to worry at all about that highly unlikely possibility. If you are worried about such things, you are more than welcome to audit the code yourself with your own time or your own money (if you hire someone of your choosing), but *not mine*. > (because it contains the same code; previously this code was compiled by TI, > now it is compiled by FreeCalypso, but the source code is the same) My FC firmware maintenance work consists of more than mere recompilation, there is also board-level hardware porting (TI's original codebase cannot possibly support a board that was conceived many years after TI closed down that business unit) and minor but important functional extensions. There is also an ongoing transition of one major fw component (the G23M protocol stack) from one TI version to a slightly newer one; the old version is in binary object form (we have no source for it), the new one came as C source, but it still has some bugs left to be shaken out. > nor legally safer than the original TI firmware? Is that wrong? It seems to me that what you are really saying without spelling it out explicitly is that in your eyes FreeCalypso has no value. If so, then it is simply not for you, and you are wasting both your time and ours by flooding our mailing list with your opinions regarding the lack of value in our work. I maintain FreeCalypso hardware, firmware and the associated host tools for my own personal enjoyment, and I make this work available to others because there are a few other odd people in the world who like it. You are clearly not one of those people, hence FOR YOU there is no value in FreeCalypso, and you are just wasting your time and ours by subscribing and posting to our list. It would be better for everyone if you simply unsubscribe and leave us alone. > Did FreeCalypso team actually read and inspect the whole parts of code > written by TI? The FC team currently has only one software engineer (that's me; the job of other current team members is to provide emotional support), and as I said above, I have absolutely no interest in expending massive amounts of time auditing the code we inherited from TI for privacy or security concerns, as those are not my areas of interest at all. > (This is also one of the reasons why I am asking about the specifications: > if there are specifications, maybe not in the form of verbal prose, but in > the form of "this low-level chip command changes chip memory this way, and > this low-level chip command sends this signal to the actual network", The "specifications" you are talking about do not exist in any written form, but they do exist in the brain wetware of OsmocomBB people who have studied TI's TCS211 firmware (while vehemently denying in public that they have ever used it), figured out how it does every hardware, DSP or radio operation of interest to them, and used this mentally reconstructed knowledge to implement their OsmocomBB layer1. > and someone is developing firmware with the intent of making it open-source > from the start, Those OsmocomBB people have done just that, but their product is not usable as an end user phone. If you wish to spend the next several years putting together an end-user-oriented phone or modem fw on the basis of OsmocomBB and make it both "information-safe" and legal, I'll be happy for you, but please note that I will never use your better fw myself, instead I will always continue using my preferred TI-based fw, as for me the personal joy of using that fw far exceeds any concerns about spying backdoors or whatever.
