| 00:03.58 | beewoolie-near | OK. Here's the wierd part. If the driver cannot open the device, it should release the resources. |
| 00:05.56 | beewoolie-near | ...except that the code is really lame and does not checking. |
| 00:06.01 | beewoolie-near | s/not/no/ |
| 00:06.35 | dyoung-zzzz | heh Like I mentioned; I just pilfered it from someplace else. :-) |
| 00:06.49 | beewoolie-near | It's not your doing. I'm reading the core 8250 code. |
| 00:06.58 | dyoung-zzzz | ok. :-) |
| 00:07.55 | beewoolie-near | Are you seeing a dmesg like this: |
| 00:08.04 | beewoolie-near | Serial: 8250/16550 driver ... ? |
| 00:08.05 | [g2] | ttyS1 works fine on the Loft |
| 00:08.13 | beewoolie-near | [g2]: With APEX? |
| 00:08.18 | [g2] | with Redboot |
| 00:08.35 | [g2] | I haven't gotten around to APEX on the Loft yet |
| 00:08.38 | dyoung-zzzz | ttyS1 works fine on a nslu2 too. Thats not the issue. |
| 00:08.53 | [g2] | the latest version of Redboot can load the kernel from ext2 on CF/Microdrive |
| 00:08.54 | beewoolie-near | I wonder if the easiest way to fix this would be to initialize ttyS1 in APEX. It shouldn't be necessary, but it might fix the problem. |
| 00:09.17 | beewoolie-near | [g2]: Well isn't that just special...:-) |
| 00:10.02 | [g2] | yeah on a new unit I just change the command string to load .... -m disk hda1:/boot/zImage and put the microdrive in and boot |
| 00:10.10 | [g2] | root=/dev/hda1 |
| 00:10.19 | beewoolie-near | cegg: I can add code to APEX to initialize the second serial port. I don't have the same kernel you have, so I cannot verify that it is working. |
| 00:10.28 | [g2] | it's really _just_ too sane |
| 00:10.48 | beewoolie-near | [g2]: I think that their -m syntax is lame. |
| 00:11.44 | [g2] | it may be but it's something that works |
| 00:11.51 | cegg | beewoolie-near: ok. where to add that? |
| 00:12.35 | beewoolie-near | I'm making some changes... |
| 00:13.25 | cegg | beewoolie-near: I have used apex-1.3.8 so far |
| 00:13.38 | beewoolie-near | NP. |
| 00:19.30 | beewoolie-near | cegg: OK. I've made the patch. How do you want to receive it? I can make a patch file. I can send a binary. |
| 00:21.07 | beewoolie-near | Actually, I think I see exactly what is the problem. Once of the uart registers has an enable bit in it. |
| 00:21.23 | beewoolie-near | It might be specific to this chip and not a generic 8250 feature. |
| 00:21.53 | beewoolie-near | What I recommend we do is try the init code as I've written it. If this work, we can remove all but the setting of that one bit to see if that makes it work. |
| 00:22.19 | cegg | beewoolie-near: email is ok |
| 00:25.36 | beewoolie-near | cegg. Did you get my dialog messages? |
| 00:26.02 | cegg | beewoolie-near: no. take johnnywhoo at gmx de (Private messages from unregistered users are currently blocked due to spam problems) |
| 00:26.34 | beewoolie-near | cegg. Right. It's easy to register. |
| 00:26.41 | beewoolie-near | Do you want a patch? or binary? |
| 00:26.54 | cegg | beewoolie-near: patch is ok |
| 00:27.16 | beewoolie-near | OK. BTW, I think that this code should really go into the kernel startup code for our target. it doesn't belong in the boot loader. |
| 00:28.08 | [g2] | beewoolie-near unless you want to use ttyS1 as your APEX console |
| 00:28.23 | beewoolie-near | g |
| 00:28.29 | beewoolie-near | [g2]: That's already accounted for. |
| 00:28.49 | beewoolie-near | Initializing the second uart isn't something that the boot loader should do. |
| 00:29.12 | beewoolie-near | Moreover, the bootloader could, and perhaps should, be able to disable both uarts once the kernel is running. |
| 00:29.22 | beewoolie-near | It will save power for systems that don't need uarts. |
| 00:29.43 | cegg | beewoolie-near: For testing purposes, it'll do. That should be done soon |
| 00:29.45 | beewoolie-near | cegg: It's on it's way. |
| 00:30.07 | beewoolie-near | Right. I'm not going to push this for now. if it works, I'll release another version of APEX. |
| 00:30.38 | beewoolie-near | The only line that should be necessary is the last one in the init code: |
| 00:30.40 | beewoolie-near | <PROTECTED> |
| 00:31.34 | beewoolie-near | In fact, that's all we ought to need in the kernel, too. |
| 00:32.05 | beewoolie-near | cegg: Perhaps you'd be better off testing the kernel with a small change to write that bit. |
| 00:32.52 | beewoolie-near | cegg: email bounced. Are you sure you gave me the right name/ |
| 00:33.32 | cegg | scheisse, replace the .de with .net |
| 00:34.03 | cegg | beewoolie-near: the rest is correct |
| 00:34.46 | cegg | beewoolie-near: received |
| 00:35.06 | beewoolie-near | It's hard for me to tell if the code is built correctly. |
| 00:35.45 | beewoolie-near | As I said, I think you'd be better off writing the single bit to the uart register in the kernel instead of hacking the bootloader. Safer and easier to test. |
| 00:36.27 | beewoolie-near | *(unsigned long*) (0xc8000004) = (1<<6); |
| 00:37.24 | beewoolie-near | Er, I think that's 0xc8001004 |
| 00:38.02 | cegg | beewoolie-near: ok. Compile & jtag will take some minutes... |
| 00:38.18 | beewoolie-near | K. I may be afk. |
| 00:39.14 | [g2] | beewoolie-near give doll-face a hug when you're afk |
| 01:03.34 | beewoolie-near | [g2]: :-) He's coming over with soup in a few hours. |
| 01:04.53 | cegg | beewoolie-near: it works! great! At least the kernel-message says so, because, currently, the jffs2-partition is dead. |
| 01:05.45 | beewoolie-near | Nice. I wonder if we remove everything except for the final line if the UART still works? Are you willing to test it? |
| 01:06.02 | cegg | beewoolie-near: yes, sure |
| 01:06.06 | beewoolie-near | thx |
| 01:06.21 | cegg | I have working jtag... |
| 01:22.18 | cegg | beewoolie-near: Ok. Seems like the last line does the job. The stripped one works too. |
| 01:22.47 | beewoolie-near | Excellent. I'll include only that line in the next release of APEX. |
| 01:22.53 | beewoolie-near | Thanks for the legwork. |
| 01:23.48 | cegg | I'll recover mtdblock4 partition to get it fully checked. |
| 01:25.21 | cegg | beewoolie-near: Well, I have to thank. |
| 02:18.25 | beewoolie-near | [g2]: hello pal it's dollface |
