Hey all,

I'm just doing this SD driver, and I'm (of course) finding the info a bit patchy.

I'm still mucking around with initialisation and I'm not sure I'm doing it right - certainly the CID numbers aren't what I'm expecting. Could anyone with some hardware and a SD card please try this prog and report the results? Note that it doesn't handle MMC cards.

I get things like this:
Code: 
Raw data = 1E41 4253 0000 4400 D602 1000 5183 0300
Manufacturer ID   = 1E
Application ID    = 4142
Product name      = S..D.
Product revision  = 88
Serial Number     = 02100051
Manufacture year  = 2030
Manufacture month = 3
which is obviously crap, well the year is anyway. Also, I get quite a few errors in initialisation like:

Manufacture year  = 2030
Manufacture month = 3
which is a bit of a worry.

To run the program, press a key to stop booting at U-Boot. Type "loads" into U-Boot, and then download the file with kermit protocol. When the download is complete, type "go 0x8000" into U-Boot and it'll do its thing.

You'll notice that it flashes the backlight 3 times and then reboots, that's just a convenience thing. I notice that the results (as in number of errors reported) is different when running from a warm boot, than running from a cold boot.

Thanks in advance!
 
try using copy/paste - it's what I used to use.

at 'gp2x' prompt type 'loads' and press enter, and then copy/paste the entire s19 file.

What are you using as a terminal? If you're on Windows, I'd recommend Teraterm, it's far better than Hyperterminal and it has Kermit download (I think).

On Linux, I couldn't find a nice windowed terminal prog so I'm using C-Kermit. It's quite awful, but it does work. I use a kermit configuration file which says
Code: 
set line /dev/ttyS0
set carrier-watch off
set stop-bits 1
set parity none
set flow-control none
set speed 115200
set prefixing all
Without the line "set prefixing all", I get errors whenever I try to download - maybe similar to your problem rlyeh?

Start the program with "kermit /home/rfbrown/config.kermit". Type "c<enter>" to go into interactive mode, and start up the gp2x. Press a key to stop the boot, type "loads<enter>", then press "Ctrl-\" and "c" to get back to kermit mode. Type "xmit /noecho /nowait /binary first.srx2<enter>" and the file will be sent. When it has finished (the command prompt comes back up), type "c<enter>" to go back to interactive mode, type "go 0x8000" to start the program.

Note that kermit has command-line history, so you can press up-arrow a couple of times rather than typing in the "xmit..." line all the time.
 
Well, if you can type "loads" and see it come up in U-Boot, I would guess that your serial port is working?

Hmmm... no ideas here. Perhaps try it with the Squidge cut-and-paste method?
 
OK, I've sorted out the CID stuff and now getting further along. Could you please try this proggie? It will (hopefully) give you output like this:

It still doesn't handle MMC cards, I'll have to look into that.

The source for the prog so far is here. You'll need a newlib/gcc/binutils toolchain as described in my GP32 pages (although you'll want a newer gcc version!), use this script to build gcc (that's if you want to use my way, you can build it any way you like). You'll also need to edit the Makefile for various paths.
 
How did you fix the byte ordering?

Ah well, a "slight" mistake in the data sheet.

In the register map for the MMC peripheral, it says the 128-bit long responses are placed in this order in the response registers: RSP1, RSP0, RSP2, RSP3, RSP4, RSP5, RSP6, RSP7 (note that 0 and 1 are reversed).

Actually, the order is RSP1, RSP0, RSP3, RSP2, RSP5, RSP4, RSP7, RSP6. All pairs are reversed!

Seems like some odd kind of endianness thing, not sure how it ended up like that but at least I understand now where I was going wrong. :D
 
pasting worked! :p

Ok,

This is a dump from my dev board with a cheap'o Viking 256MB SD.
I did not bother with MMC's but I have a few so I can test if you want.

No idea about your flashy LCD light trick Rob, no LCD to look at ;-).
