* Speakup and PCI Express Serial Cards @ Trevor Astrope ` Kirk Reiser ` Adam Myrow 0 siblings, 2 replies; 16+ messages in thread From: Trevor Astrope @ UTC (permalink / raw) To: speakup Hello again, I'm still having trouble detecting my Dectalk Express with the latest speakup. This time I'm using FC12 with kernel 2.6.31 with speakup 3.1.5 from git as of yesterday. The issue is that the Dectalk cannot be found. I get the error below. FATAL: Error inserting speakup_dectlk (/lib/modules/2.6.31.9-174.fc12.x86_64/speakup/speakup_dectlk.ko): No such device The serial port is provided by an Axxon pci express card. I can communicate with the Dectalk in minicom with the serial port set to ttyS0 and 9600,n,8,1. The [:ver speak] command will result in the Dectalk speaking its firmware version. So, I know the serial port works, but for some reason speakup is unable to detect the Dectalk. Note, I've also tried a vanilla 2.6.32 kernel as well as a modified 2.6.18 rhel5 kernel. I'm pretty confident that this isn't kernel related, but speakup or hardware related. Likely a combination of both, since I presume others are using the latest speakup with the Dectalk Express. Is anyone able to help? I have a spare pci express serial card I can provide to anyone willing to help. Thanks, Trevor ^ permalink raw reply [flat|nested] 16+ messages in thread

Have you checked to make sure the speakup_dectlk.ko module is actually at that position in the path? That looks more like a modprobe error than a speakup one. You might also try running depmod -a to make sure it's in the database. I've found that sometimes modules_install's depmod doesn't quite cover the situation correctly.

Yeah, I thought the location was odd too. But it is indeed installed there. -rw-r--r--. 1 root root 222333 2010-01-14 10:03 /lib/modules/2.6.31.9-174.fc12.x86_64/speakup/speakup_dectlk.ko I tried depmod -a again, but I still get the same result. The main speakup module does get loaded, so modprobe does appear to be finding the module. To be sure, I also tried insmod and get the same "No such device" error. I'm curious if anyone else is using a hardware synth over a pci express serial card to know if this situation is unique to me. Kirk, I'm in Montreal, so it would be easy for me to send the card to you if you have the time.

Hi Glenn, I got the card from <http://www.softio.com>. The company is called Axxon though and I got the single port pci express card. I don't recall the price and model, but I can find out when I'm back at the office on Monday. It is based on an Oxford chip and I think the price was around $30 or $35 USD. It is a Canadian company, but they charge in USD. There are also other manufacturers who make pci express serial cards based on the oxford chip. Searching for "pci express serial card" on google will turn up a few results. Keep in mind that I haven't been able to get it to work with my dectalk and speakup. I have an extra one that I am willing to donate to anyone who is willing to work on getting speakup to work with it.

Unfortunately, I'm sure this is his issue. The problem is that we have the ports and irq numbers hard coded into speakup, and we access the hardware directly instead of using linux tty devices to do so. This is one of the issues that still needs to be fixed before we can submit speakup to become an official part of the kernel; we need to convert over to use linux ttys. If we were doing that, he would not have noticed a difference. William ^ permalink raw reply [flat|nested] 16+ messages in thread

For those following along in the ongoing saga of Trevor versus speakup and the pci express card, here is the latest chapter: I last left you after modifying serialio.h and hard coding the values for my pci express card. This had no effect. Well, after checking a little closer, the hard coded values for SERIAL_PORT_DFNS is in an #ifndef, so it seems it is defined elsewhere. Trevor not being a C programmer, let alone a kernel developer, changed that #ifndef to a #ifdef to see where it is defined. Turns out, in my case, it is defined in /usr/src/kernels/2.6.31.9-174.fc12.x86_64/arch/x86/include/asm/serial.h, and what is more, it is defined the same way as it is in serialio.h. Taking up thy keyboard, I carefully change the first entry to look like this: { 0, BASE_BAUD, 0xCC00, 16, STD_COM_FLAGS }, /* ttyS0 */ \ I then do the ever so familiar, make clean; make; make modules_install; and add another depmod -a, just for luck. But alas, it is all for not. I still only hear silence after connecting my dectalk express and invoking the modprobe speakup_dectlk command. Desperate times, calling for desperate measures, I once again roll up my sleeves, take a deep breath, and once again delve into the speakup source code... I notice some print statements that are commented out in serialio.c, so I uncomment them in hopes of getting some more information in the logs. For those who are still following along and are just dieing to know what they are, I won't keep you in suspense... 75 /*printk(KERN_ERR "in irq\n"); */ 76 /*pr_warn("in IRQ\n"); */ There are some others, but they aren't important for now. At first, I did not see anything else being printed in the logs. In the time honoured tradition of, "what happens when I do this," I commented out these lines in serialio.c: 41 if (synth_request_region(ser->port, 8)) 42 return NULL; Once again, after the make clean; make; make modules_install; ritual, followed by the modprobe speakup_dectlk invocation, with the depmod -a thrown in there for luck, you'll never guess what happened... I heard the following in a slow and drawn out, but still familiar voice, "Dectalk Express found." But where is the rest? No prompt, no nothing. Hit enter a few times, but only my old friend, silence. I told you that you wouldn't guess. I did find those print statements I told you about in the logs though, so I do feel I'm getting closer. I feel I only need to figure out what synth_request_region(ser->port, 8) means, and I'll be a little closer... I will beg upon the mercy of the speakup developers and offer them a gift in the form of my logs and hopefully I will be rewarded with some enlightenment.
