REV A P2 Edge booting from flash possible?
Hi, First time I've tried it on this board but am having problems booting an old REV-A P2-Edge board from flash. I can see the flash from my app when loaded and running from a RAM download and I can also write to it with loadp2 but it refuses to boot from flash for some reason. I've got the pull up and down icon dip… -
Re: Propeller 2 Assembly Language beginner guide v0.1
Yes, good to hear things are working out. I remember an early period of learning where I first worked out the structure of Z80 instructions. How the opcode and associated operands were consecutive ordered bytes. That simple detail was a revelation at the time. Of course I didn't yet know the terminology at that stage. It… -
Re: REV A P2 Edge booting from flash possible?
Flexspin is mainly about C Lib. If you're using Z80 assembly with incorporated FS then that doesn't really fit. -
Re: Use of long, word, byte, res in inline assembly Solved. RET needed!
Thanks all for the clarifications! I can't find an appropriate definition of this. I presume it refers to what the PASM manual calls 'Effects'? Else I am missing something (Again...) I remember that... -
Re: Use of long, word, byte, res in inline assembly Solved. RET needed!
Instruction prefixing does take up extra code space. An example of prefixing is the AUGx instructions. They modify the subsequent instruction. _RET_ is a built-in option of most instructions, like CC modification or conditional execution. No extra code to have these. PS: The Z80 was famous for its instruction set… -
P2ASM Sharing HUB RAM location between cogs?
Hello, I'm new to the propeller platform, but I've got a fairly extensive track record with assembly programming on other architectures (ARM, AVR, 6502, Z80). I'm having issues trying to share hub memory locations between cogs. And let me preface with I do not want to use spin2. I can't say that I'm a fan of there seeming…
