PCIe serial card problem

Hi everyone
We are using tx1 jetpack3.2.1.
We have a netmos9904 pcie serial card, the card has four serial ports.
In the kernel we found the drivers/tty/serial/8250/8250_pci.c file is the dirver for it.
We change the CONFIG_SERIAL_8250_NR_UARTS and CONFIG_SERIAL_8250_RUNTIME_UARTS from 4 to 10.
After the kernel bootup, we try to write to the /dev/ttyS1 but got “Input/output error”

  Could anyone give us some ideas to debug this, thanks a lot!

we use cat /proc/tty/driver/serial the information as bellow:

root@tegra-ubuntu:/home/nvidia# cat /proc/tty/driver/serial 
serinfo:1.0 driver revision:
0: uart:Tegra mmio:0x70006000 irq:320 tx:163151 rx:953 RTS|CTS|DTR|RI

8: uart:unknown port:00000000 irq:0
9: uart:unknown port:00000000 irq:0

setserial -g /dev/ttyS* show as shown below

nvidia@tegra-ubuntu:~$ setserial -g /dev/ttyS*

/dev/ttyS8, UART: unknown, Port: 0x0000, IRQ: 0
/dev/ttyS9, UART: unknown, Port: 0x0000, IRQ: 0

here is is the kernel dmesg info

Compiled in drivers/net/wireless/bcmdhd

I can’t help much, but some initial information may be useful.

Keep in mind that when you query a UART you are really querying the driver, and the driver may not have a means to actually read what the UART is doing…the response you get might be what the driver was told to do regardless of whether the UART can actually do it. It wouldn’t be unusual for an “unknown” UART to function correctly.

You will want to post the output of “sudo lspci -vvv”.

The UARTs appear to share the IRQ 368. The other is an integrated Tegra UART. Those UARTs appear as ttyS1 through ttyS4, which may be a problem.

Understand that the TX1 has its native drivers set up in part via the device tree, but PCI will have its own method of setup which does not use the device tree. The two will not necessarily know about each other and may not cooperate.

In the scheme of the native UARTs the “compatible” entry for each serial UART controller names which drivers the UART can use. As an example:

compatible = "nvidia,tegra114-hsuart";

In one case the driver is a standard 8250 style UART driver (with emulation for 16450, 16550, and 16550A), and in the other driver there is a DMA capability added. When the older 8250 style driver is used the naming convention will use the “ttyS#” naming, and when the DMA driver is used the UART will use the non-conventional “high speed” naming “ttyHS#”. For a native controller case, “ttyS0” and “ttyTHS0” (“THS” is “Tegra High Speed”…in “compatible” device tree “hsuart” is “high speed uart”) are the same hardware, but viewed with two different drivers. It’s probably a bad idea to use both drivers at the same time, the result would be undefined. Both device special files can exist, but I wouldn’t advise actually using both at the same time.

The older 8250 style driver is all that U-Boot understands, and so serial console uses this both in U-Boot and once the Linux kernel is loaded (this is “/dev/ttyS0” which is the same hardware at the end of “/dev/ttyTHS0”). Most of the UART examples you find for a TX1 will use the “ttyTHS#” instead.

There are other UARTs in a TX1 beyond ttyS0/ttyTHS0. For example, J17 on the dev carrier is accessed as “/dev/ttyTHS2”. This is the same hardware as “/dev/ttyS2”.

Do you have a custom carrier board? Or is this the default dev board kit? Assuming the latter, then unless you did something to disable the other UARTs of “/dev/ttyS1” through “/dev/ttyS4”, I would guess that there is a conflict.

You may want to research your specific driver and see if there is a way to move them to “ttyS5” through “ttyS8”. Or you might consider using the device tree to disable conflicting native drivers. Or perhaps you could remove the non-high-speed drivers from the “compatible” list.

Disabling the native UARTs would be something like editing the device tree where you go to the “serial@” of those drivers, and set “status” to be:

status = "disabled";

…I’m not certain, but “disabled” could be “<0x0>;” instead…it depends on the driver as to what the disabled syntax is.

Did you happen to connect the card to an x86 system and see if the same procedure works there? If not, please get the correct procedure (from the manufacturer if required) and try with it.
From the log, it looks nothing wrong from PCIe side and only the procedure seems to be the issue here. Also, can you please confirm if the driver is bound with the device correctly? (by dumping ‘sudo lspci -vvvv’)

Hi linuxdev,vidyas:
Thank you for your patience and help. We have found the resolution from the github(https://github.com/Kedia94/MCS99xx-driver-for-TX2)
By unbind the serial driver in kernel and then insmod the 99xx.ko from the github, the card can send and receive data with rts and cts open.
It is strange that if we remove the {PCI_VENDOR_ID_NETMOS, PCI_DEVICE_ID_NETMOS_9904} in the pci id table recompile the kernel and then insmod the 99xx.ko driver ,it still could not work normally.
Anyway, the problem has been basically solved, thanks a lot for your help

Hi liuke:
Can the card send and receive data?
we use EXAR pcie to uart, By unbind the serial driver in kernel ,insmod .ko,There are device files /dev/ttyXR0 and /dev/ttyXR1,But unable to send data,I’m typing at the terminal:
sudo echo 123 >/dev/ttyXR0 …blocking;
But everything works fine on x86,Why,Do you kown?
Does this have anything to do with CONFIG_SERIAL_8250_NR_UARTS and CONFIG_SERIAL_8250_RUNTIME_UARTS?

I don’t know the requirements of that card. There may indeed be specific kernel driver or features required, but if the device special files show up, then that means the driver has loaded.

Serial ports, and the programs using them, tend to need to agree on settings. For example, if you have hardware flow control on, but only echo text to the port, then nothing will show up until you assert the CTS/RTS correctly.

As a test you can use loopback. Take the physical port associated with ttyXR0, and jumper TX to RX, as well as CTS to RTS. Then try to see if a serial console program can see an echo of whatever text is typed. I use gtkterm (“sudo apt-get install gtkterm”). To check at 115200 8N1 without flow control (it doesn’t hurt to have or not have CTS/RTS when the UART is told to not have flow control enabled):

sudo gtkterm -b 8 -t 1 -s 115200 -p /dev/ttyXR0
# ...now type text and look for an echo...

Within gtkterm you could then enable CTS/RTS flow control if you wish.

Hi linuxdev:
Thank you for your advice,insmod .ko I see log,On x86,only successful initialization information is displayed,
The interruption occurs when I enter echo …
But,On tx2,In addition to the successful initialization information,there were several interruptions,There are no more interrupts when I enter echo …
All go into interrupt handlers

hi wawxh1101:
Does your card use netmos99xx chip? We found the same problem with netmos99xx chips on other arm64 platform chips(hi3559a, rk3399 etc).It seems like the pcie bar0 is used for io space, bar1 is for mmio, but the default driver 8250 set port.iotype = UPIO_PORT using bar0 which lead the card could not be used on arm64.But they all can be solved by remove the default driver and insmod the ko. So we did not spend much time on this problem.

Hi liuke:
Thanks,we use EXAR’s XR17V352 chip ,we also remove the default driver and insmod the ko,but can’t send out the data…Let me think it over.

I’m unsure of the meaning of “The interruption occurs”. Are you speaking of a literal stop of IRQ (which would imply a locked up or failed driver)? If that is the case I couldn’t tell you what the failure is, but #liuke reminds me that DMA and other aspects of the driver may need to change when going from x86 to arm64. If there is a literal driver failure where IRQs stop upon echo, then I’d have to wonder if the driver was properly ported to arm64 (is the driver one which ships with 64-bit ARM, or was this added from some outside code source?).

Thanks linuxdev,help me troubleshoot problems,but I don’t think the reason is DMA or anything,Here are some logs:

insmod ko,had twice irq,There was no more interruption ,I don’t know why. The card is to transfer 485/422, Dest not tx support?

There isn’t enough to go by here, but if you’re really using RS-485, then there is more to control than with RS-232. You might want to post the exact serial card you are using, but what I know is based on RS-232. RS-485 starts adding shared bus cooperation to what RS-232 provides (RS-232 does not share a bus).

Or if using RS-422, you would still need to add more details. Regardless, I suspect there is more configuration required for using this card than is required for the average serial UART.

I see a lot of speed settings going on in dmesg, but I have no idea how many ports the card has, nor what extra setup is required as RS-485, nor do I know what else is talking to the bus. I may not be able to help, but to find out you’ll need to provide the exact topology of what ports this card has, and to what each port is connected. Without that I doubt anyone would be able to help.
