Dear TI Team,
We have a design with AM3354. In our board we are using UART1, UART2, UART3, and UART4 to communicate with our external devices. As known, UART0(ttyS0) is used as console terminal and we are able to see the debug messages on that port. However, we are also able to see the debug messages on UART3 after device is up. In our use case, we will send/receive some set of commands to/from our another board over UART3(ttyS3). While some commands are sending properly, on the other side some of them are received not properly, actually some characters are missing in the commands. Below you can see our message body.
Here, our main question is related with console terminal. Normally it must not be seen or available on UART3 port but currently it is.
We are suspecting from a wrong configuration at our side but dont know which side is wrong. Can you pls. help on to debug this issue?

I try install the runit into the linux RT.
I have read the google.
As I understood:
When I compile the runit in x86 (ubuntu 16.04 LTS), the compiler found the "-lgcc_eh" and "-lc" in "libgcc.a" and "libgcc_eh.a" files at "/usr/lib/gcc/x86_64-linux-gnu/5" directory. So, it compile finely.
When I compile the runit in arm (linux RT Arago 2018.04), the compiler can not find the "-lgcc_eh" and "-lc":
/usr/lib/gcc/arm-linux-gnueabi/7.2.1/../../../../arm-linux-gnueabi/bin/ld: cannot find -lgcc_eh
/usr/lib/gcc/arm-linux-gnueabi/7.2.1/../../../../arm-linux-gnueabi/bin/ld: cannot find -lc
the compiler tried to find "-lgcc_eh" and "-lc" in files at "/usr/lib/gcc/arm-linux-gnueabi/7.2.1/../../../../arm-linux-gnueabi/bin/ld".
The file "libgcc.a" is in "/usr/lib/". But there are no any "libgcc_eh.a" file at rootfs.
Please help.

Matching Question between TDA2SXBTQABC(SOC) and TPS659039(PMU):
1. We used following PMU(TPS659039 Orderable device: O9039A387IZWSRQ1; Device Mark: TPS659039 OTP 87 1.3) to match DRA756 for early project.
2. New ADAS project will choose TDA2SXBTQABC(SOC), we know PMU description is PO9039A387IZWSRQ1 on DRA74xDRA75xTDA2xCPU Board Schematic Rev H_sprr210(VAYU EVM);
Please help us to confirm same PMU(TPS659039 Orderable device: O9039A387IZWSRQ1; Device Mark: TPS659039 OTP 87 1.3) can match with TDA2SXBTQABC(SOC) ?
Are PO9039A387IZWSRQ1 and O9039A387IZWSRQ1 same PMU ?

Tool/software: TI-RTOS
Hi,
I am using CCV7 and ti-processor-sdk-rtos-k2hk-evm-04.03.00.05-Windows-x86-Install.
We have designed the custom board using 66AK2H14 . In which Micro semi Ethernet switch(VCS7429) is connected to the SGMII ports of the K2H processor.
2. SGMII to SGMII with Forced Link Configuration:
Whether there is any limitation from 66AK2H14 processor side for forced link configuration?
Is there any changes other than what is specified in section 2.4.3.4 SGMII to SGMII with Forced Link Configuration of the GBE user guide for forced link configuration?

Hi Experts,
My customer tries to use Ethernet on TDA2Px RVP. But Ethernet doesn't work. They don't see "NDK: Link Status: 1000Mb/s Full Duplex on PHY 12". Also, if they ping from the machine, no response returned.
They are using Radar SDK 3.04 with their modifications. Following is thier cfg.mk settings for ethernet.
#
# Supported values: ipu1_0 none
#
FATFS_PROC_TO_USE=none
#
# Supported values: ipu1_0 ipu1_1 none
#
NDK_PROC_TO_USE=ipu1_1
#Used to control TFDTP stack (supported only when NDK_PROC_TO_USE = ipu1_1)
NSP_TFDTP_INCLUDE=yes
Do you see any issues?
Best regards,
Ken

Hello , I have met a problem about com port, and I need your help , thanks
platform : AM3352 / USB to 4UARTS
(1) The following is some info which you may need :
root@Adv335x:~# uname -a
Linux Adv335x 4.14.79-rt47-g28d73230da #2 PREEMPT RT Thu Feb 21 01:31:12 PST 2019 armv7l GNU/Linux
root@Adv335x:~# lsusb
Bus 001 Device 002: ID 0403:6011 Future Technology Devices International, Ltd FT4232H Quad HS USB-UART/FIFO IC
I use the usb to 4 UARTS of FT4232H Quad High Speed USB to Multipurpose UART/MPSSE IC , and the driver seems to work well,
TI SDK is the lastest version : v05.02 but ti sdk has two version of PROCESSOR-SDK-LINUX-AM335X and PROCESSOR-SDK-LINUX-RT-AM335X.
and I have test both the version of rt and non-rt.
the problem is that PROCESSOR-SDK-LINUX-AM335X works well while PROCESSOR-SDK-LINUX-RT-AM335X has the warnning all the time when I use the COM port.
And I need to use the PROCESSOR-SDK-LINUX-RT-AM335X version, so please help me to sovle it , thanks
and here is the boot warning log:

Sir,
Can I power MITYDSP L138 using JTAG connector(XDS100V3) while programming USING CCS
Part Number:AM3359
The cycle time for TXC was removed from Table 7-20 on the datasheet which is changed from SPRS717J to SPRS717K.
Is this a typo?

Hi,
I am using pdk_k2g_1_0_6 and trying to run USB host application on the K2G board. One pen drive (16 GB Sandisk 3.0) works fine, but the other pen drive(same model but 32 GB) is not getting enumerated properly.
The sequence in the code is CONNECt event-> PORT RESET -> Enable Slot. The last command is not getting completed. I have observed the same behavior on another sandisk 2.0 pen drive(16GB). Can you suggest anything?
Thanks,
Krishna

Hello Experts,
We tried compiling the network tool with latest SDK.
we have updated with the proper toolchain path in RULES.MK and COMMON_HEADER.MK files
But network tool compilation failed with below logs.

Hi,
I have seen example for PCIe write_loopback for EP and RC for TDA2xx RTOS. How can we make this to communicate two TDA2x boards, one EP and one RC ?

Hi all,
I'm using C674X processor, i have the updated AISgen reg settings,
I learnt from this link,
you can configure the AISgen for the SDRAM/EMIFB length
which is also set on the gel file.
The code works for extended SDRAM on the debug mode, with the changes made to the gel file configuration.
But doesn't work when flashed on the boot, which means it needs some added settings.
Can someone guide me, how it can be set on the AISgen file
or is there anything else i'm missing to configure?
would appreciate any help.
Kind regards,
NJ
I'm using AISgen for D800K05, app to generate my ais file from the generated output file.
Part Number:TMS320C6678
Tool/software: TI-RTOS
In my application, C6678 read a lot of data from FPGA through EMIF16. I configure the read time as 5 EMIF clock cycles. It costs 5 cycles with one read as I configured.
But there are about 20 cycles between the two READ actions. This cause the average read speed is very low.
Between the WRITE actions, there are no the extra cycles. And the write the speed is high.
How to eliminate the extra the 20 cycles between the READ actions?
Read(5cycles)---(20cycles)---Read(5cycles)---(20cycles)---Read(5cycles)---(20cycles)---Read(5cycles)

Hello *!
Connect a single PHY to one EMAC is no problem:
&cpsw_emac0 {
status = "okay";
phy_id = <&davinci_mdio>, <9>;
phy-mode = "rgmii-id";
dual_emac_res_vlan = <1>;
};This is working fine.
But now we have to use a switch behind the cspw... therefor the "port 0" (from Linux view) of the KSZ9893 have been set to "PHY Mode" and I can see the 3 ports over MDIO:
[ 1.951119] davinci_mdio 48485000.mdio: phy[0]: device 48485000.mdio:00, driver unknown
[ 1.959219] davinci_mdio 48485000.mdio: phy[1]: device 48485000.mdio:01, driver unknown
[ 1.967329] davinci_mdio 48485000.mdio: phy[2]: device 48485000.mdio:02, driver unknown
(Driver unknown: If a use a simple homebrew driver on base of KSZ9031, it will be probed... BUT: Port0 will get something like a PHY ID: 004040FE...? The other will be shown as 221637 as expected...? Okay, only sidekick information. I go on:)
There is a driver for KSZ9893 (in our case) I took from mainline Linux and backported it to our 4.4.84 Kernel. Microchip placed it to "DSA"-part of network driver.
I never used a switched like this with DSA... I tried some silly first hook:
&cpsw_emac1 {
status = "okay";
switch@0 {
compatible = "microchip,ksz9897";
port@2 {
reg = <2>;
label = "lan6";
};
port@1 {
reg = <1>;
label = "lan3";
};
port@0 {
reg = <0>;
label = "cpu";
fixed-link {
speed = <1000>;
full-duplex;
};
};
};
Of course... it do not work.
Is somebody able to tell me, how it works using a switch behind the cpsw_emac...
Maybe somebody used KSZ9897 (or similar?) behind TDA2+ and would tell little secrets?
I'm running out of ideas right now... an out of time, too.
So: Thank you! Every help is welcome....
Part Number:TMS320DM8148
We are using a TMS320DM8148 and 'DM8127 with sensor that supports four exposure WDR and we need to determine if the SOC can make use of this feature. That is, can TMS320DM8148 take four frames of different exposures from an image sensor and combine them into one higher dynamic range image?
Thanks
