your question allocation has been taken up
I recently found out about Allwinner SoCs. I am not an electrical engineer, I am studying computer science at the moment with a strong personal interest in PCB design and making circuits with some kind of processors involved. I did some simple 2-Layer boards with 8-Bit controllers in the past. I am happy with it but I want to go the next step and design something with a "real" CPU and connection to SDRAM & Flash.
it's a statement :P
I neither have the equipment nor the money to solder / route BGA components. I read about the A13 which comes in a TQFP package - but it needs DDR2 RAM (I think?) and that's only available in cheap as BGA. So I kept on searching around until I read about the F-Series CPUs, which are quite old. They are based in ARM5 and ARM7. But I thought that going with something older is probably easier to get into designing a more complex P
I thought "Well, there must be more information out there if one could adapt the linux kernel to this specific processor series, it is not possible to write a linux kernel with 30 pages of documentation"
Here I am asking if anyone has more information about the F-Series chips? Being more specific: the "F1C100A" which is available as 128-TQFP on aliexpress for 2$. It supports slow and old (perfect for me) SDR-RAM and also has enough other peripherals on board (such as SPI, I²C, UART) and also enough GPIOs left to drive simple parallel displays
So yea :D
one of the problems you would face is that you would need to get the chips made again
@DonkeyHotei I don't need a reliable source of those chips - I basically just want to get one or two demo boards running for personal amusement
They are still available at aliexpress, so...they are still out there :)
The main reason why I want to work with them is their more simple RAM interface, as I said they support SDR-SDRAM which is available in TSSOP package
Maybe if no one has any documentation you could at least help me to figure out how to search through the linux sources and find the specific parts of the source code which are responsible for the F-Series processors
Why would Allwinner give any documentation to the open-source linux team but not to the rest of the world? I don't get it.
pcbBob_: I would say if your serious you should idle around and see if maybe someone here could inquire for you for them or has them, but since a lot of people are in different time zones in different places, you probably will not get the answer your looking for immediately.

TheBug I don't mind not getting my answer the moment I ask my question. I will look around from time to time and ask the same question again :). I hope it doesn't bother anyone. There are only 5 page of google results for "F1C100A" and I clicked on every single link
If it helps I could also buy a few of those chips and ship it to anyone living in (central) europe if that helps.
