Seriously, you should look at the Baking Pi tutes, they aren't that difficult and you will pick up ARM code quite quickly if you forget x86 and the way that works.
ARM code is one of the leanest and neatest instruction sets I've used (and that is quite a lot). Learn the instruction set and you will get used to it. I've been using it on and off since the very first ARM chip was released
you are quite right rpdom, I did understood what HEX_adddict was trying to do, but obviously his thinking wasn't actually based on factual information. I stand corrected.rpdom wrote:Actually, sector 0 contains an MS-DOS style MBR and partition table. It can be used to boot quite a few OSen on a PC, but the boot block isn't used at all on the Pi, apart from possible to identify the fact that it is an MS-DOS type MBR and has a valid partition table.
The only bit that the Pi needs in it is that partition table to show that the first partition is FAT and where it is and how big.
No executable code is used from sector 0.
Hardly!So, I'm alone.
Ah, those were the days. Yes, CD was the call instruction and C3 was the jump instruction. 00 was noop. I can't remember any of the others these days, but it has been a long time (goes all misty eyed now).mahjongg wrote:I remember a colleague that could read a hex-dump of ZX80 code, as if it was assembler. Me, I never remembered more than that "C9" was the return instruction and "CD xx yy" was the call instruction (if memory serves me well).

Ok, great. Good luck.HEX_addict wrote:I need only one month to read books of Assembler for x86, one month to makesmall exercises in ASM, and one month to programming the server.
Enough that you don't want to own that "machine", but you will (probably next year after you'll finish reading ASM book) outsource the production to one of the existing factories in this business.HEX_addict wrote:how much cost me a machine who can build me my own processor/SOC and my own Raspberry Pi?

Interesting idea... To what blocks would you break down the RasPi to get this kit ?HEX_addict wrote:If a company will sell a kit to make your own Raspberyy Pi, i will change the world.

Perfect choice ! HEX is actually the best selection for coding and maintaining.HEX_addict wrote:I cane make every kind of program, but only in HEX.
C'mon... don't waste your potential with printing a character on the screen.HEX_addict wrote:If u find time, put here the code in HEX and ASM, to print a character on screen.

Best of luck, it's taken Linus (and an army of acolytes) since 1991 to get their OS to the current status. So I'll look forward to your new super secure OS appearing in 2037.
