Issue with RS485 using 7,E,2 serial moving from sitara SDK 8 to TI processor SDK 2.00.1

Ed Boyer

Other Parts Discussed in Thread: TPS65217, PCA9534, LM75A

We are in the process of moving from the last sitara sdk (8 I believe) to the latest TI Processor SDK (2.00.1). We use the omap_uart (omap-serial?) driver to automatically handle the 485 half duplex control. Back in the old sitara sdk this worked with serial formats 8N1 and 7E2, but in the latest sdk we only see 8N1 function and not the even parity. The normal RS232 port still works fine for both formats, so it seems to be specific to the 485 function. Was a bug introduced into this driver or am I overlooking something?

compatible = "ti,am3352-uart", "ti,omap3-uart";
ti,hwmods = "uart2";

Prodigy 100 points

Some more information. Have tried 7E1 as well, but it appears to be a combination of even parity and 485 regardless of stop bit 1 or 2. It also appears that an occasional serial transaction does get through, I've seen it as unlucky as 1 in 30 or as good as 50%. Verified that under the old sitara sdk I can go 10 for 10 under the same serial settings. I've also attached a log of the boot up. I've been trying to revert portions of omap-serial.c but hard to tell if I'm getting any improvement.

Hi,

I have asked the software team to look at this. They should post feedback directly here.

Hi,

Just an FYI, Sitara SDKs switched from omap-serial to 8250 driver after 08.00.00.00. If you are trying to rework the omap-serial.c, you need to modify the kernel defconfig file, see: processors.wiki.ti.com/.../Sitara_Linux_UART_-_Switching_to_8250_Driver

Best Regards,
Yordan

We did build with the old omap serial support. The 8250 was debated, but at the time we thought we were mitigating risk. I did briefly try a build with 8250 but I suspect device tree bindings may be different as the 485 did not work initially (I did rename the ttyOx to ttySx). It does appear that sections of 485 support have moved up into higher source files in the transition from 3.14 to 4.1 (such as serial_core), so I can only guess at what level things may be tripping up. So far it seems to be the combination of 485 and even parity.

0 Ed Boyer over 9 years ago in reply to Ed Boyer

Actually looking at 8250 omap, I can't see evidence of 485 support in it at present. Looks like there may be some proposed fragments of patches to add 485 to 8250 omap, but not sure what kernel they may be meant for. lkml.org/.../587 At this point not sure whether to keep looking at omap-serial, try to get 485 into 8250 omap to see if issue exists there, or try to get by on the old sdk for the duration.

For clarification our customized am335x uses the following uarts.

UART0 - RS232 system console

UART1 - RS485 application

UART4 - RS232 application

Under the old sitara sdk, both application ports work fine at both no parity and even. Under the new sdk, 485 with even parity only works rarely to occasionally, however the RS232 port functions cleanly for both parities and 485 with no parity seems fine. I've had the application log the bytes it is reading, it appears that bytes are being lost when using 485 with even parity. Has changes to the drivers regarding 485 perhaps lead to erroneous parity errors? However I did try clearing both IGNPAR and PARMRK in the application and the missing bytes are simply not there versus having \0 bytes in their place.

Hi,

I checked the 8250 driver, and indeed there is no support for rs485, yet. I also checked the latest mainline release v.:4.5, and couldn't find anything related to rs485 ported in 8250_omap.c. I have no information when and if, support for this interface will be available in TI releases.

Since porting the rs485 functionality in kernel 4.1 could be quite time consuming, for the time being , I'd suggest to stick with the older sdk & omap_serial driver.

Best Regards,
Yordan

The thing driving us into the new sdk is that out in the public repos is a workaround for the tilcdc sync lost issue (aka "snowcrash" e2e.ti.com/.../1653040 ). So at the moment it appears we either need to try to back port that workaround to the old sdk, or attempt to revert the serial in the present sdk to a point where 485 worked with even parity. As the 485 issue is quicker to test for than the video, I've been looking over the serial this morning. Seems like there has been changes both in regards to flow control and 485, but nothing obvious as yet. Though perhaps I'm jumping to the conclusion that the serial is easier than the video and it may be the reverse (my knowing very little of the mechanics of linux drivers).

Yordan,

Unfortunately using the older SDK is not a good option. The fixes being implemented for the DSS are required to fix other issues. Is there an option to roll back the omap serial driver and still use the latest SDK?

485 functionality is pretty critical for a large number of customers. If this is not in the errata/issues list for the SDK would it make sense to add it?

Regards,
Matt

Hi Matt,

matt minga said:

Here is what I did, and it seems that kernel is initializing both UART0 (as a debug console) & UART2 (configured with customers dts node as RS485) with the omap_serial.c driver:

Test platform is BBB, running SDK02.00.01.07 (kernel 4.1.13).

In dts I added:

uart2_pins: uart2_pins {
pinctrl-single,pins = <
0x150 (PIN_INPUT_PULLUP | MUX_MODE1)
0x154 (PIN_INPUT_PULLUP | MUX_MODE1)
>;
};

&uart2 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&uart2_pins>;
rs485-rts-delay = <0x5 0x5>;
rs485-rts-active-high;
linux,rs485-enabled-at-boot-time;
};

In tisdk_am335x-evm_defconfig file I did the following changes (taken from older sdk, which uses omap-serial):

#
# Serial drivers
#
#CONFIG_SERIAL_EARLYCON=y
CONFIG_SERIAL_8250=y

# CONFIG_SERIAL_RP2 is not set
# CONFIG_SERIAL_FSL_LPUART is not set
# CONFIG_SERIAL_CONEXANT_DIGICOLOR is not set
# CONFIG_SERIAL_ST_ASC is not set

I added the following prints in omap_serial.c to be sure that the driver is inserted in kernel 4.1.13:
int ret;

+ printk("####BEGIN OMAP_SERIAL DRIVER####\n");

/* The optional wakeirq may be specified in the board dts file */

if (pdev->dev.of_node) {

...............

ret = serial_omap_probe_rs485(up, pdev->dev.of_node);

+ printk("####PROBED RS485 SUCCESSFULLY####\n");

if (ret < 0)

goto err_rs485;

As a result kernel on BBB indicated:

[ 0.311039] ####BEGIN OMAP_SERIAL DRIVER####
[ 0.311117] omap_uart 44e09000.serial: no wakeirq for uart0
[ 0.311138] ####PROBED RS485 SUCCESSFULLY####
[ 0.311298] 44e09000.serial: ttyO0 at MMIO 0x44e09000 (irq = 155, base_baud = 3000000) is a OMAP UART0
[ 1.041905] console [ttyO0] enabled
[ 1.045967] ####BEGIN OMAP_SERIAL DRIVER####
[ 1.050484] omap_uart 48024000.serial: no wakeirq for uart2
[ 1.056354] ####PROBED RS485 SUCCESSFULLY####

Which indicates that both uarts (debug console & UART2) are being used by omap_serial.c. This configures the system to omap_serial.c in kernel 4.1.13

I don't have much experience with rs485 interface, so could you try these modifications?

Yordan

Regarding your other question:

We don't have the plans for future SDK releases. I've asked the factory team in the internal discussion on this. I will post the feedback from them, as soon as there is one.

This morning I tried rolling back the entire serial folder as just reverting omap-serial didn't seem to get it. I had to flip defines from CONFIG_PM_RUNTIME to CONFIG_PM. However it did compile and the issue seems to no longer be there. I have run a loop of about 6000 485 transactions with 7E2 with no drops. Something in the serial driver system from then to now must be causing the issue with 485 even parity. I will attach a zip of the serial folder I stuffed in there. I will have a look at your post and compare it with our present configuration.https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/791/serial_2800_mod_5F00_old_2900_.7z

Yordan,

Thank you for the response. We have been running on the omap serial driver already. Switching between the driver versions is not the issue. The question was related to rolling back the kernel sources to allow the 485 to work properly. Ed's response below is more along the lines of what we were talking about doing.

Generally we like to check with TI or anyone who might no better what the risks are of making changes to drivers.

Regards,

Matt Minga

Overall are settings are similiar. We turned off the CONFIG_SERIAL_8250 option entirely. I will attach our full config file and decompiled device tree. Our DT pin control is specified a little differently.

Hi Matt,

It should be ok to back port the RS485 functionality from kernel3.14 & config the kernel to use omap_serial.
Some things I noted:
1. in kernel 3.14 they use *up (i.e. up->rs485.flags) to configure the uart. In kernel 4.1.13 they use *port (i.e. port->rs485.flags). IMO you should keep the *port pointer
2. In kernel 4.1.13 in serial_omap_config_rs485() function of the omap_serial driver, there is a spin_lock() removed:
spin_lock_irqsave(&up->port.lock, flags);

/* Disable interrupts from this port */
mode = up->ier;
up->ier = 0;
serial_out(up, UART_IER, 0);
Be careful with that, as it may lead to a deadlock in your kernel. Consider adding back the lock (either mutex or spinlock) to the uart port.

3. In kernel 4.1.13 you may need to add back the serial_omap_ioctl() function in omap_serial. Without this it is probable to get unaligned access when you try to use the RS485 from user space.

Hope this helps.
Best Regards,
Yordan
