Hello,

I am currently trying to figure out how to integrate FFTW into CCS. I am using the ti-processor-sdk-linux-am335x-evm-06.00.00.07. I am trying to incorporate the SDK examples with FFTW.

This is the error I am getting:

I made sure to include the fftw3.h in my project.

Here are my include files:

All I have in my code is the header file:

Is there any suggestions anyone can provide? I can compile/run the FFT code I wrote using FFTW, but for some reason I can't run the code on CCS. An example command I use to compile the FFTW code in a terminal is:

gcc fftw_example.c -Wall -lfftw3 -lm -o fftw.example

Do I need to add the -Wall, -lfftw3, -lm, and -o commands to a makefile in CCS?

Best Regards,

Tyler

I'm using Runtime Object View (ROV) and I see the following:

Is this a problem or expected behavior? Can you please give more details?

Note: the same is show in ROV Classic.

What should I do to let my app can recognize keyword interrupt? Right now my app can't recognize keyword interrupt and compile failed.

Hi,

 I try to debug some SDO upload request (expedited) of specific index at specific slave address that don't work.

Soon we figured out that the address that we send to the PRU and the one on the "wire" was not the same.

As far as I can follow the address, his value is as wanted:

UINT8 MBX_CopyToSendMailbox( TMBX MBXMEM *pMbx )
{
    if ( (nAlStatus & STATE_MASK) == STATE_INIT)
    {
        /* the mailbox is disabled if the slave is in the INIT state */
        return( ERROR_INVALIDSTATE );
    }


    if ( !bMbxRunning )
    {
        /* the mailbox is disabled if the slave is in the INIT state */
        return( ERROR_INVALIDSTATE );
    }

    if ( bSendMbxIsFull )
    {
        /* mailbox service cannot be sent because the send mailbox is still full */
        return MBXERR_NOMOREMEMORY;
    }
    else
    {
        /* the variable mbxSize contains the size of the mailbox data to be sent */
        UINT16 mbxSize = pMbx->MbxHeader.Length;
        PRINTLN("HW_EscWriteMbxMem at addr: 0x%X", pMbx->MbxHeader.Address); /////////////////////////////// output:  HW_EscWriteMbxMem at addr: 0x3EA
        HW_EscWriteMbxMem((MEM_ADDR *)pMbx, u16EscAddrSendMbx, (mbxSize + MBX_HEADER_SIZE));

Hello,

Is it possible to run FFTW on the linux SDK? If so, how can I do this? I am using version 06.00.00.07. The best information I can find is here: https://www.mccdaq.com/PDFs/Manuals/DT7816_WebHelp/Build_the_FFTW_Library.htm

However, the documentation is limited and it doesn't really tell me how to do this for the AM3358.

Does anyone have any suggestions?

Best Regards,

Tyler

Currently working at new board design.

I`m investigated sitara TRM on-chip debug support chapter.

There are little about system trace and EMU pins. I`m found that xds100 and xds200 do not support core and system trace without ETB. But main question about XDS560v2 that supports 1-4 pin system trace and XDS pro trace that supports 1-20 pins STM trace.

Should i need route EMU2-EMU19 pins from AM5749 to 60 pin mipi jtag header?

may be better to route 20 pin jtag header?

I have a UDP program running on BBBlack and it transmits and receives fine, however, if the packet stop for a few mins and then restart it take ~ 10sec or so before packet start being transmit or it give the host down error code. There is not keep alive time for UDP, so why is the stack seemly shutdown?

Hello,

I am trying to compile FFTW code on CCS. However, when I try to build the project, I get the following build error below due to a linking issue:

I believe I have FFTW installed correctly because I am able to compile my FFTW code using the following command in the terminal:

gcc fftw_example.c -Wall -lfftw3 -lm -o fftw.example

I am currently using ti-processor-sdk-linux-am335x-evm-06.00.00.07 with Ubuntu 16.04.

Any suggestions are greatly appreciated.

Hi,

I'm trying to connect Sync link with VPE link. 

The output of sync link is Video composite buf type. 

When i connect links and execute it, the vpe link display the error message that it can receive only Video frame buf type.

Could you let me know if there is any solution to connect sync link and vpe link?

hi experts,

i have the TI EVM board TIDEP-01002 , visionsdk version is 0304, now i can boot the visionSDK ipu firmware by bootloader,

i also port lp8860 back light driver in spl. during the uboot period i can see animation on the srceen, 

but after go into booting kernel, animation show was aborted, nothing can show on the screen, but 

the back light also keep turning on and IPU on M4 side working well, not crash.

i check the lp8860 registers' values. it is all correct. I guess it is the GPIO problem,

but i had added the following configs in DTS.

#define DISABLE_PRCM(label) &label { ti,no-idle; ti,no-reset-on-init; }

DISABLE_PRCM(gpio2);
DISABLE_PRCM(gpio6);
DISABLE_PRCM(gpio7);
DISABLE_PRCM(dispc);
DISABLE_PRCM(dss);

so i dont know where is the problem, could you help me figure out the problem?

if i boot the IPU firmware by remoteproc module in kernel, and port the lp8860 driver in spl, it will work very well.

best regards!

We are working on a custom board based on AM3359. Our board is booting successfully and working fine.

But PING is not working and data transfer is also not happening..

While I was searching in the internet, I came across the below link and based on that I am here posting all the details and logs regarding our custom board.

Hi, in SPRACK7B  table 1, the AM5718 supported PMIC stated is TPS6590379, I wonder if TPS6590378 is supported or not? 

Because in the datasheet of AM5718 SR2.0, only PMIC TPS659037 is mentioned to use, but does not specific OTP version. And in SLIU011F  table 1, the TPS6590378(OTP 0x96) is listed support AM571x. So please help to confirm?

Hello,

I'm using processor sdk linux 5.02 for am5728.

Here are pinmux for DCAN2 generated from online pinmux utility.

	{GPIO6_15, (M15 | PIN_INPUT)},	/* gpio6_15.dcan2_rx */

Trying to setup CAN2 module in below manner.

I've found a same thread where problem is near to the mine but he can set triple-sampling mode on and i cannot.

Is there any pinmux related mistake.

I want to test the board with LTP-DDT, but I can' t fetch this by git clone. Can you give me a .zip file for LTP-DDT?

Part Number: AM3356

I am using DMA for i2c communication

During read and write i am facing data corruption issues.

I have enabled MMU.

I have observed during my debugging that at certain times the data corruption happens.

I have used the following API's during read/write

1) After i2c DMA read used CleanInvalidateDcache();

2) Before i2c DMA write CleanDcache();

When i disable MMU, i am not facing the data corruption issue. 

Please let me know is there any issue while using DMA with MMU enabled.

Thanks for the help in advance

Part Number: DM3730

Hi,

I am  developing a camera for road traffic applications.Output from the sensor is analog.

I need a processor with parallel camera/sensor interface and I have selected

DM3730. Processor should be capable of running Image processing application that detects vehicle presence. 

Does DM3730 meet my requirement?.Please advise me regarding the selection of processor.

If you have any other processor with parallel camera interface that meets my requirement,please suggest.

Dear Champs,

Per below post, a patch is applied to kernel to support early boot late attach. The patch is to disable EDMA setup in kernel since EDMA has been setup in M4.

    https://e2e.ti.com/support/processors/f/791/t/826484

From c11eef98b07a8c9093f2f5c71f8ba40451559e86 Mon Sep 17 00:00:00 2001
From: Shravan Karthik <shravan.karthik@ti.com>
Date: Mon, 31 Jul 2017 10:24:20 +0530
Subject: [PATCH 2/4] arm: mach-omap2: Remove edma related nodes from hwmod
 init sequence

When doing late attach, kernel should not reset EDMA
EDMA is setup by M4 and thus omap_hwmod needn't perform reset/setup.
Nodes 'dra7xx_l3_main_1__tpcc', 'dra7xx_l3_main_1__tptc0' and
'dra7xx_l3_main_1__tptc1' are thus disabled.

Note that this breaks kernel boot if not late attached.

I think the failures comes for device tree because the default device tree still try to setup EDMA

		interrupts = <GIC_SPI 371 IRQ_TYPE_LEVEL_HIGH>;
		interrupt-names = "edma3_tcerrint";
	};

My questions:

1. Sould I modify the device tree by removing the EDMA setup? Or I can just leave it unchanged and ignore the EDMA failures?

2. Per below post, TI has provided a EDMA kernel space driver. When using early boot late attach, EDMA is setup in M4 not A15. I would like to know if this driver can still work in such case.
