What CF cards are supported? #292

I'm using MK4_rom.bin on a Mark IV.
I've tried a few CF cards: some work, some don't.
Some UDMA 6 cards work and some don't.
UDMA 7 cards don't work.

Does the BIOS use PIO or UDMA?

PIO
Mode 6 - 25MB/s
Mode 5 - 20MB/s
Mode 4 - 16.7MB/s
Mode 3 – 11.1MB/s
Mode 2 – 8.3MB/s
Mode 1 – 5.2MB/s

UDMA
Mode 7 - 166MB/s
Mode 6 - 133MB/s
Mode 5 - 100MB/s
Mode 4 - 66.7 MB/s
Mode 3 - 44.4MB/s
Mode 2 - 33.3MB/s
Mode 1 - 25MB/s

What cards are supposed to work?

Thanks for the debug rom.

FYI This is what the (working) 8GB SanDisk Extreme 60MB/s UDMA 6 CF card looks like with IDETRACE set:

All cards should work. There are no known CF Card software incompatibilities.

RomWBW uses PIO to access CF cards. All cards should be PIO compatible (I have not encountered any that are not).

The typical issue with compatibility has to do with the CF Card interface. Newer/larger cards tend to have very fast signal transitions that are not always handled well by the hardware interface. The standard RC2014 CF Card module is particularly problematic because it has no signal buffering.

What platform are you using? What version of RomWBW are you using?

If you are comfortable building a custom ROM, you can add the following line to your configuration file to enable detailed debug output for CF Cards:

IDETRACE .SET 3

I'm using Mk4_rom V3.0.1 on a Mark IV

OK. I have had pretty good luck with that hardware interface. It does require that the CF Card support 8-bit I/O, but they are all supposed to do so.

Do you want me to send you a pre-built ROM image with the debug output enabled?

Thanks,

Wayne

No, I should be able to build that myself :-)

Great. I should be able to tell from the DEBUG output at startup what is happening with specific cards. If it is hardware, you will typically see that the card is unresponsive to attempts to wake up and initialize the card. If there is a software protocol issue, you will see some packet exchanges followed by something going wrong.

Feel free to forward any debug output.

Thanks,

Wayne

I checked out tag/v3.0.1, ran the build on Mac OS. The Build completed with no errors but the rom is not the same as the rom in the binary distro and it doesn't boot.
I could try to debug the MacOS build but might be easier in the short term if you send me a rom with idetrace turned on.
Still up for that?

No problem. I have attached a zip file that includes the ROM image (.rom) with IDE debugging enabled. I tried it on my Mark IV system and it worked as expected (got debug output).

The zip file also includes a .com version of the build. If you have a way to transfer this to your system, you can run the .com file under CP/M and it will load the debug ROM on-the-fly without burning a new ROM. There are scenarios where this mechanism will fail, so don't worry if that happens. Just revert to programming the ROM.

Note that the provided build is based on the current dev branch. This branch is quite stable and is probably best for testing the CF Cards.

Let me know how you do.

Thanks,

Wayne

Thanks Graeme,

Indeed this indicates a hardware incompatibility with the failing cards. The first card is performing perfectly. The second two are not responding at all. I have a couple cards that are also failing like yours. These cards also fail under John's UNA BIOS, so there are multiple BIOSes that fail, so I'm pretty sure it is hardware. I have tried various changes in the RomWBW BIOS and nothing seems to get these cards working. These cards DO work fine when I plug them into a Dual IDE board in the Mark IV. Again, points to a hardware interface issue on the CPU card's CF Interface. Wish I had a solution, but I don't. This interface is going to always prefer older cards.

This is the line from your working card that shows it is responding:

IDE0: PROBE E0 50 [50 E0 00 00 01 01 01] [50 E0 00 00 01 01 01] 50 01 01 00 00

These are the lines from your failing cards that show they do not respond at all:

IDE0: PROBE E0 00 [00 00 00 00 00 00 00] [00 00 00 00 00 00 00] 00

Thanks,

Wayne
