Virgil Dupras 7cdc288ef2 zasm: print progress indicator while assembling 2019-06-19 11:42:39 -04:00
Virgil Dupras 66fbd20e21 sdc: tidy up 2019-06-19 09:24:16 -04:00

Virgil Dupras 6df77ddef3 recipes/rc2014/zasm: we can now assemble the recipe's kernel 2019-06-18 22:07:44 -04:00
Virgil Dupras 2ac16d4750 sdc: check CRC during sdcReadBlk 
When there's a mismatch, retry up to a certain number of times.

This makes random problem related to assembling big kernels go away! But
it also make SD card reading much slower...

Virgil Dupras cac9acca67 sdc: make some space in memory for buffer CRC 2019-06-18 15:21:58 -04:00
Virgil Dupras 34db493496 sdc: implement CRC7 computation on cmds 
For now, this achieves nothing else than wasting cycles, but this is the
first step in enabling CRC verifications (CMD59).

I think that this is where my random problems with assembling large
kernels from SDC come from: bad data that isn't detected. If that
happens when PGM loads programs in memory, then anything can happen.

`sdct`, when ran often enough, will error out or corrupt away (go
crazy)...

Also, tighten RAM addresses. They were unecessarily loose.

Virgil Dupras 00778f73e1 blockdev: fix bug recently introduced in load cmd 
It would always load one byte less than told... This time it's right on
the money :)

Virgil Dupras 4b423a9dc6 tools/blkdump.py: new tool 
Also, rename "download.py" to "memdump.py".

Virgil Dupras 8cf9904f33 blockdev: fix load command over-loading a byte 
Calling `load` would always read one more byte than specified. Also,
make `0` mean `0x100`.

Virgil Dupras bd2877e012 shell: make arg in peek/poke mandatory

Virgil Dupras 7c23e5a9ef acia: protect DE during aciaInt 
I don't know why I haven't noticed it wasn't protected. It must have
been behind many random problems I've been having...

Virgil Dupras 4327153ffd zasm: fix include EOF detection 
That was an interesting bug. It didn't cause a problem in emulation, but
in an RC2014 on an SD card, an include that didn't end with two newlines
would cause an infinite loop.
 2019-06-15 15:50:27 -04:00
Virgil Dupras 92a04f4627 sdc: support 24-bit addressing 
Needed if we want to compile the kernel and zasm from within a SD card.
I didn't go straight for 32-bit because it was significantly more
complex and 24-bit give us 16M. Enough to go on for a while...
 2019-06-15 13:41:20 -04:00
Virgil Dupras 605c631dc0 shell: add support for backspace 
It doesn't sound like much, but that backspace key is often useful...

Virgil Dupras 14cc2fb785 parse: fix option word default value 
Previously, an optional word argument would only have its first byte set
to zero.

Weren't properly saved during local pass back and forth.

Virgil Dupras c613f7b0ee recipes/rc2014/eeprom: fix broken a28w args passing 
That's why the command seemed slow! It's much faster than I thought.

Virgil Dupras 817636242a Add at28w app and recipe 
This allows us to write to an AT28 EEPROM from within collapse os.

Virgil Dupras 145b48efb7 Add apps/sdct 
A new app to stress test the SD card driver. Also, accompanying this
commit, changes solidifying the SD card driver so that stress tests
actually pass :)

Virgil Dupras 495d69c1cb sdc: make writing more solid 
By not waiting until the SD card wan't busy any more after a write, we
exposed ourselves to errors if another operation was attempted right
after it.

Virgil Dupras a7ce9f6fc6 pgm: adapt to recent blkdev change 
With fsGetC becoming a "random address" API, it broke pgm. This commit
fixes it. To avoid adding the weight of a blkdev in pgm, I manage the
read offset directly in pgm.
 2019-06-05 14:45:38 -04:00
Virgil Dupras c18d42f08b fs: further adjust to previous blkdev refactoring 
Previous refacoring broke all seek/tell within fs. fs handles now lost
the responsibility to keep track of current position. It's blkdev's job.
 2019-06-04 20:45:01 -04:00
Virgil Dupras ae028e3a86 blockdev: make implementors "random access" 
This huge refactoring remove the Seek and Tell routine from blockdev
implementation requirements and change GetC and PutC's API so that they
take an address to read and write (through HL/DE) at each call.

The "PTR" approach in blockdev implementation was very redundant from
device to device and it made more sense to generalize. It's possible
that future device aren't "random access", but we'll be able to add more
device types later.

Another important change in this commit is that the "blockdev handle" is
now opaque. Previously, consumers of the API would happily call routines
directly from one of the 4 offsets. We can't do that any more. This
makes the API more solid for future improvements.

This change forced me to change a lot of things in fs, but overall,
things are now simpler. No more `FS_PTR`: the "device handle" now holds
the active pointer.

Lots, lots of changes, but it also feels a lot cleaner and solid.

Virgil Dupras 63473cc2e3 blockdev: make selection structure opaque 
I'm about to change that structure and I don't want fs to be messed up
by this. I'm proceeding step by step...
 2019-06-04 09:56:36 -04:00
Virgil Dupras c85ed474d7 blockdev: remove _blkCall 
The ability to specify "0" routines in blkdev table is not used anymore
now that stdio is a separate subsystem.

Also, I'm preparing a blockdev refactoring and this complicates my work.
