Part Number:AM4379

Tool/software: TI-RTOS

Hi folks,

I have the EtherCAT_Slave_full_AM437x_arm Demo running on my idk4379 board with a custom ESI-file.

I also have achieved to get the IO-LINK Master Demo running with hardware like TIDA-010016.

Now i want to combine Both of these Demos to have IO-Link Data on EtherCAT available running one Part on PRU0 and the other part on PRU1.

1. So which hardware changes on idkAM4379 i have to do to archieve this ?

2. Also how can i get both of these demos running one on PRU1 and other on PRU0 ?

3. How to intercommunicate  between these two PRU's    

thx in advance

Hi everyone!

I tried to separate DSP core context execution, I explain:

I would like to affect for instance the following range:

CORE0 : 0xB000 0000 - 0xB0FF FFFF,

CORE1: 0xB100 0000 - 0xB1FF FFFF.

The idea is only core0 could read, write data in its area, core1 shouldn't. It is the same for core0 who shouldn't read or write in core1 area.

How to do that ?

I currently tried to map this sections by MPAX register of DSP corePac. But I think I miss something. I post my code at the following of this post.

Best Regards,

François

Dear Experts,

could You please help with a clarification on EDMA3 transfer completion indication, which is manually triggered and used in a non-interrupt fashion --> polling.

Basically the question is, whether it is enough to use the "EDMA3_DRV_checkAndClearTcc()" function as confirmation, that EDMA3 transfer was successful?

Maybe there are other events, interrupts, arbitrations, which could abort an on-going EDMA3 transfer impacting IPRH bit and thus it seems, that transfer is complete, while actually there was an error or similar ...

I assume enabling and handling the error interrupts and error status registers mentioned in the KeyStone Architecture EDMA3 Controller Users Guide in addition to above "EDMA3_DRV_checkAndClearTcc()" function should be enough or are there any other conditions/situations to consider?

Many thanks and best regards,

Gregor

Hi all,

If the DSP and ARM access share memory or DDR at the same time, which one has higher priority?

Thank you.

The data sheet shows the following…

Min delay time and Max delay time are specified as percentages of clock cycle. Specification is given for tc min of 6.06ns (165MHz). However, customer operate at 148.5MHz which has a tc of 6.73ns. Normally expect min and max delay to be fixed. Thus as the clock rate slows down timing margins get easier to meet. By making the percentages this does not happen in the same way.

Is it correct to define them as percentages of 148.5MHz? This would mean …

Min Delay = 6.73ns * 0.27 = 1.82ns

Max Delay = 6.73ns * 0.8 = 5.39ns

allowing minimal incremental gain by slowing the clock

In Errata Advisory 2.1.47

Workaround: There are two options for a workaround:
1. The external device connected to the HDVPSS interface can capture data on the
rising edge.
2. External logic can be used to invert (or delay) the clock to provide adequate setup
and hold times to meet the requirements of the external device.

for #1 a max delay of Tc*0.8 is impossible to capture data on rising edge

Also this advisory states that HDPVSS Out only supports falling edge clock and points us to SPRS614F for more information. SPRS614F makes no mention of this, so there is a lack of clarity to the timing on this interface.

Need clarification since datasheet and errata have invalid information

Hi,

I would like to know how to define a port and number PIN of the a GPIO. Where I can find more info of this...

I found GPIO configuration code which makes LED1 = 0x603 (port and number incuded). Where come that number (0x603) from ?

Best regards.

I opened and asked this question in the past where it wasn't resolved and that case was now locked. I am reaching out again here as this is a must have feature for us now. From the previous thread, the problem was the function that handle file IO fileIOCmdHandler(UInt32 cmd, Void *pPrm) in network_ctrl_handle_mmc_wr.c

I have added Vps_printf in both SYSTEM_LINK_CMD_OPEN_FILE and SYSTEM_LINK_CMD_WRITE_FILE. The problems:

1. in  SYSTEM_LINK_CMD_OPEN_FILE, fileIOPrms->fileName, fileIOPrms->fileMode are corrupted. The fileName should have been AppImage while fileMode: "wb"

2. In SYSTEM_LINK_CMD_WRITE_FILE, both fileIOPrms->dataAddr, fileIOPrms->dataSize are 0 

Please help look into why this is the case. This function can be tested on your own TDA3 setup.

Thanks,

I have tried setup AM437x HS for setup unit to verify the secure boot feature, however I have this issue, could you please help?

I tried to fix it without success. Here is the problem description:

The system does not boot up. After 30 seconds of powering up, the display shows faint vertical lines. Note that the microSD card (inserted) is programmed correctly since I can use it to boot up another EVM.

The EVM board PN is TMDXEVM437XH**SD-CUBIC

Hi Team,

Our customer have questions for his TMDSIDK437X evaluation board on controlling the stepper motor:
1. How to use this board to connect and control any stepper motor.
2. Do he needs to buy any extra tools to help with the process. Is there any available example to help with this?

Thanks!

1. We are going to have the following IPv6 UDP traffic, is any way to handle it reliably within the time limits:

• 8x 1.1kB packets sent out (with future growth to 30x or 40x 1.1kB packets) with no reply expected. Our current design needs this to finish within 500 microseconds.
• 8x 90B packets sent out, each with an associated 1.1kB packet reply received
• Ethernet:

• 1x 90B packet sent out with an associated 1.1kB packet reply received, or
• 1x 1.1kB packet sent out with an associated 90B packet reply received

All of this traffic needs to occur (and complete) every millisecond. The system we are communicating with is able to process and reply within a couple microseconds (not counting transport time). For this interface, we are using eth1 direct-connected to an FPGA over RGMII, there are no PHYs.  Is any way to handling it properly?

2. How to tell what speed the kernel cores are running at?  If it is set in u-boot. Shall we use the same u-boot as the AM572x EVM board, so what speed is that running?

Note: We are currently using the ti-processor-sdk-linux-rt-am57xx-evm-05.00.00.15-Linux-x86-Install.bin SDK with slight modifications to match our design.

Could you please advice and help us resolve these issues?  Thanks!

Part Number:AM1806

Hi,

According to the Silicon Errata for AM1806

http://www.tij.co.jp/jp/lit/er/sprz314h/sprz314h.pdf

at chapter  “2.1.5 System-Level ESD Immunity Usage Note”, the following design is recommended.

However, load current to X1 could be about 12.5mA if the above design is implemented.

12.5mA is too big, and the waveform may become loose.

And also, because of the following condition is satisfied 

Voh(out out of X1 High) < Vih(threshold of incoming high to AM1806)

then unexpected behavior could be occurred.

Question 1:

Why so little resistance are recommended to R1, R2?

Question 2:

What is the recommended Crystal oscillator for X1?

Best regards,

HaTa.

Please help me in board-bring up for customized am3352 processor. I want to boot kernel from DDR2 which has 256MB size start adddress 0x80000000 to 0x90000000. Please let us know how to boot with DDR instead of from NOR flash. I dont want to boot or store images in NOR flash. Just for testing

Built uImage with make LOADADDR=0x82000000 uImage .Generated uImage and followed following step.

a. flashed SPL image got window uboot#

b. uboot# tftp 0x80000000 u-boot.bin

c. uboot# tftp 0x82000000 uImage

d. uboot# tftp 0x90000000 am335x.dtb

f.  uboot# bootm 0x82000000 0x84080000 0x90000000

Also tried without initrd.uboot bootm 0x82000000-0x90000000

After following above step kernel struct at "starting Kernel ...."

Kernel version 3.14 and 4.14 but it boots perfectly from NOR flash by storing images in NOR flash.

Please help me to boot Kernel from DDR directly also i have zImage also.

Waiting for your response.
