Part Number:AM5718

Tool/software: TI-RTOS

Hello Experts,

I am trying to compile the SBL for only idkAM571x executing "gmake sbl LIMIT_BOARDS="idkAM571x" 

But it looks like it compiles all the boards in PDK as error shown below. 

C:/ti/pdk_am57xx_1_0_12/packages/ti/board/board_cfg.h:66:54: fatal error: ti/bo

                                                      ^
compilation terminated.

gmake[1]: Leaving directory `c:/ti/pdk_am57xx_1_0_12/packages/ti/boot/sbl'

How can we limit the sbl compilation to a particular board?

Part Number:AM6526

Hello, I've been searching for an ARM Processor with USB 3.0 and found the AM6x family of processors. I'm planning a design in which I must store 1-Gigabit ethernet data to a removable memory, such as a USB 3.0 thumb drive or to CFAST 2.0 Compact Flash card. So, I found the AM6526 ARM processor that has two ARM cores and USB 3.1. Can anyone tell me when the AM6526 device will be available?

Thanks,

TMS320C6713B: Code execution from flash directly

Part Number:TMS320C6713B

Hi,

I am working on c6713 processor. its kind of old chap. the code runs from IRAM (internal RAM). On boot, the processor copies 1k of code from CE0 region (NOR flash is mapped here) to IRAM. The remaining code needs to be copied using a bootloader. My question is it possible to run code directly from flash (mapped on CE0) rather than copying the code to internal RAM (IRAM)  and then running it from IRAM in c6000 family?

Kind Regards,

Ijaz

Linux/PROCESSOR-SDK-AM437X: AM437x LPDDR Timing issue

Part Number:PROCESSOR-SDK-AM437X

Tool/software: Linux

Our product is based on AM4376 and consists of LPDDR2 (ELPIDA 4Gb).
With the existing EMIF configuration tool, there was no problem in DRAM initialization when configuring DDR3, but there is a problem with LPDDR2 configuration.

When I use generated emif value , even single read/write access is failed.

But when I changed the CL (Cas latency) of SDRAM_CONFIG to 0x2 (Invalid value) then single read/write works
However, in burst operation with LDMDIA / STMIA, only the initial 4 words read is returned correctly.

Is there an updated emif tool and should I use something other than u-boot code in process-sdk (ti-processor-sdk-linux-am437x-evm-05.02.00.10) when using LDDDR2?
(I have checked dpll(266Mhz) and io config ...)

RTOS/AM4378: Ethernet phy link reset at startup with HSR/PRP firmware in PRP mode

February 24, 2019, 2:24 am

Part Number:AM4378

Tool/software: TI-RTOS

Hello,

We have a custom board with the AM4378 and dual ethernet phys DP83822IF connected to the PRU MII interface. We run the HSR/PRP firmware release 01.00.02 on the PRUs in PRP mode.

When the TIRTOS starts the phy link gets reset, e.i. the speed and link led turn off and we get a link down interrupt, multiple times and we observe TCP retransmissions on the NDK side. After a few minutes the link stabilizes and we don't see any link drops after a month of continuous operation. This does not happen every time and it depends on what type of network we are connected.

If we disable the NDK stack from starting and let the HSR/PRP switch tasks run the link is not reset. If we interrupt the MDIO connection to the phy the link is not reset.

Currently it seems that for some reason the HSR/PRP firmware on the PRU resets the link on the phys via MDIO. We haven't checked the contents of the MDIO communication during link resets yet.

Does the PRU firmware for HSR/PRP have the ability to signal the phy over MDIO to reset the link?

If it does, what are the circumstances in which this happens?

Kind regards, Marko

Looking for schematic or help with: 20e_cTI-14t_TI Pin Converter

Hello,

I have got an Blackhawk BH-560M. But without the attached 20 pin JTAG-Cable.

The "20e_cTI-14t_TI Pin Converter" is of course also missing.

I do not need 50 MHz JTAG Clock. So i want to build my own cable.

From the pictures its a simple Pin-to-Pin-converter.

So the levelshifter and the other needed active circuitry seems to be already in the box.

Can someone be so kind and check the 20 pins on one side to the 14 pins of the other side?

I would need this only for the DSP parts.

Best Regards

Hi,

I bought a camera module from TI for my rev3 EVM board recently. From other threads in this forum, it should work with "dual camera demo" example directly, but it didn't in my test.

I tried to modify the buffer type from V4L2_BUF_TYPE_VIDEO_CAPTURE to V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE in the example code. It can finish initialization, but end in a core dump.

The output of the original "dual camera demo" example:

Looking forward to your advises. Thanks a lot.

Hi everyone,

What is the value of WLEN and FLEN when QSPI communication is executed for the QSPI memory map port

by executing the following codes (A) and (B)?

(A) 
uint8_t *pSrc; /* Source address */
uint8_t *pDst; /* Destination address */

count = 3;

while(count)
{
    *pDst = *pSrc;
    pDst++;
    pSrc++;
    count--;
}


(B) 
uint32_t *pSrc; /* Source address */
uint32_t *pDst; /* Destination address */

count = 3;

while(count)
{
    *pDst = *pSrc;
    pDst++;
    pSrc++;
}

I'd like to know where the frame ends.

Best regards,

Sasaki

But, I think that two chips are operated.

If you know anything about this, please let me know.

AM3352: Is there a timing requirement for total input power-on time Tr and VCC and communication interface?

Part Number:AM3352

Hi team,

             I have some questions about AM3352  timing sequence application:

1. Now the VCC5V is used as the total input in the design.

   How long does the Tr rise time need to be greater or less to ensure normal operation?

For example, when Tr > 1ms, you can work.

2. The communication interfaces used now are RX/TX and DP/DM.

Do VCC and RX/TX or DP/DM signals have strict power-on timing requirements?

For example: VCC5V power on first, it must be Delay 10ms before DP/DM can signal out.

thanks.

Hi,

I have a question regarding the on board EMAC of AM3359. If I am not wrong, according to datasheet this MCUshould have 2 EMAC ports capable of 10M, 100M and 1G Ethernet connections. I know that two MACs available on ICE 2.1 EVM board are accessible via PRU-ICSS. My question is whether in general there is a hardware capability of using additional 2 EMACs if a custom board was used (not ICE EVM board)?

Thank you in advance.

What will happen if this sequence is not followed?

Example)
Device breaks
Device does not start up

Figure 6-2. Preferred Power-Supply Sequencing With Dual-Voltage I/Os Configured as 3.3 V

G. If all the 1.8-V supplies are not sourced from the same power supply, it is required to power up VDDS before other
1.8-V supplies. Further, it is also recommended to source VDDS and VDDSHvx [x = 1-6] when configured as 1.8V
from the same power supply.
