Their asm code has been broken for a little while! oops!

Virgil Dupras 495d2819d2 recipes/rc2014/sdcard: make spi relay design multi-devices 
Also, fix the SPI relay driver to properly AND-away the result of
the CTL read.

Tested with a real prototype, works fine.

Virgil Dupras 7dc00179f7 tools/upload: use A! instead of C! to write 
By default, it changes nothing, but it allows interesting
setups, such as using AT28! for directly uploading to EEPROM.

I've also updated the EEPROM recipe to upload directly to 0x2000.
I'm not sure what has changed, but it's working fine now.

Virgil Dupras 1a6a549857 Make the SPI Relay protocol support multiple devices 
Working on programming AVR chips exposes a glaring omission in my
first design of the SPI Relay: not allowing multiple devices make
this task hard. I constantly have to unplug my SD card before, plug
the AVR chip holder, then play a bit, then unplug the AVR holder,
then replug the SD card...

My prototype for a SPI relay design is built, but I haven't tested
it yet. I need to adapt the code first, which is what I do here.

When the prototype is tested, I'll update the SDC recipe with a new
schema.

Virgil Dupras 46676547d9 spi: add SPI_DELAY decl 
AVR chips often run at less than z80's system clock. This means that
our SPI relay needs to have its own clock to properly communicate
with it. This means that the delay between OUT and IN can't be
hardcoded to 2 NOPs anymore. It needs to be configurable.

Virgil Dupras 124da6adec Move SD Card subsystem outside of RC2014 recipe and add protocols 
Although the SPI Relay driver is RC2014-specific, the SD Card driver
is generic enough to be a subsystem. That's the second subsystem we
add and this warrants, I think, the formalization of a new concept:
protocols.

Virgil Dupras b8e52707e9 recipes/arduinouno/at28: improve reliability 
Previously, it could never write more than a few bytes before pingpong
getting a mismatch error. Now, I can pingpong Collapse OS binary
without a mismatch.

Virgil Dupras f09aa0603c rc2014: separate SPI relay and SDC drivers 
My intention is to reuse the SPI relay to program AVR MCUs from a
RC2014.

Virgil Dupras 3068b58be5 Rename RAMSTART to SYSVARS 
It's more descriptive this way. Also, I'll soon add a new HERESTART
config.

Virgil Dupras 1312817117 z80: make boot binary a 2-part process 
Previously, recipes that began spitting binary contents before
loading block 282 would end up with VARIABLE code in their binary,
thus breaking them. We fix this by making this loading process
2-part.

Virgil Dupras 496826cdc4 pcat: implement AT-XY 
VE works! well, at this point, we can say that Collapse OS runs on
PC/AT. A little cleanup and docs writing and we're done!

Virgil Dupras dc7f36263a pcat: BLK-enabled! 
That INT 13H logic was a bit tricky to implement...

read-only for now.

Virgil Dupras 99c05fff3c pcat: it works! 
Forth intepreter now works! There's still DOES> and overflow checks
to implement, but otherwise, we have it!

Virgil Dupras 60ecab314e pcat: we have PROMPT! 
Not working, but we do get that sweet "CollapseOS".

Virgil Dupras 6bc1738bfd pcat: implement (loop) 
8086 asm is a lot terser than z80... Those indirect memory operations
are very handy.

Virgil Dupras d8d2e05eb2 pcat: make find compare strings 
find is the biggest chunk of logic of the boot code. The 8086 version
is significantly terser than the z80 one. REP/CMPS helps...
 2020-06-15 06:23:19 -04:00
Virgil Dupras 8c452f5add pcat: begin implementing find 
Not comparing strings yet. Without asm tooling support, it's a big
chunk to swallow at once. It's progressing well!
