Hi,
Let me talk about ACD of EtherNet/IP for AM3356.
ACD status should be send to Master for EtherNet/IP certification.
Could you tell me your advice how to implement to send ACD status to master ?
I understand TI does not release this SDK including ACD implement.

TMS320C6678: dsp c6678 meory write latency Comparison: Hyperlink VS. Internal Memory
Part Number:TMS320C6678
Hi,
Detail about the question is as below:
My test condition:(Latency Measurement)
1. Hyperlink 4 lane @ 3.125Gbps/lane
2. DSP write a 8 byte data to destination.(both local address and hyperlink address tested)
3. Noncacheable, Nonprefetchable
4. No other peripheral enabled
5. following time was measured:
-- Time write then read back
-> Get Timestamp
-> Write a special pattern to destination
-> once the read back value match with special pattern, get timestamp
-> two timestamp difference is the Tw+r
// write then read data latency measurement //Clear cache CACHE_wbInvAllL2(CACHE_WAIT); cycles= TSCL; *hyperlink_address = 0x000000004C100000; for (;;) {
if ((*hyperlink_address) == 0x000000004C100000) { cycles= TSC_count_cycle_from(cycles); break; } } iThroughput= (unsignedlonglong)8*DSP_Core_Clock_KHz/cycles/1000; printf("%5d MB/s, copy %d bytesto 0x%x then read back, consumes %ld cycles\n", iThroughput, 8, hyperlink_address, cycles); Hyperlink_write_then_read_cycles = cycles; |
-- Time Write only
-> Get Timestamp
-> Write another special pattern to destination
-> Get timestamp
-> two timestamp difference is the Tw
// write data latency measurement //Clear cache CACHE_wbInvAllL2(CACHE_WAIT); //CACHE_invAllL1p(CACHE_WAIT); cycles= TSCL; //MemCopy8(dstBuff, srcBuff, uiByteCnt/8); *hyperlink_address = 0x1234567890ABCDEF; //if((Uint32)dstBuff>=0x60000000) //DDR // CACHE_wbL2((void *)dstBuff, uiByteCnt, CACHE_WAIT); cycles= TSC_count_cycle_from(cycles); iThroughput= (unsignedlonglong)8*DSP_Core_Clock_KHz/cycles/1000; printf("%5d MB/s, copy %d bytes to 0x%x, consumes %ld cycles\n", iThroughput, 8, hyperlink_address, cycles); Hyperlink_write_only_cycles = cycles; |
-- Time Read only
-> Get Timestamp
-> once the read back value match with special pattern, get timestamp
-> two timestamp difference is the Tr
// read data latency measurement cycles= TSCL; for (;;) {
if ((*hyperlink_address) == 0x1234567890ABCDEF) { cycles= TSC_count_cycle_from(cycles); break; } } iThroughput= (unsignedlonglong)uiByteCnt*DSP_Core_Clock_KHz/cycles/1000; printf("%5d MB/s, read 8 bytes from 0x%x, consumes %ld cycles\n", iThroughput, hyperlink_address, cycles); Hyperlink_read_only_cycles = cycles; |
-- Latency calculation
-> Tlatency = Tw+r – Tw - Tr
Hyperlink_write_latency = Hyperlink_write_then_read_cycles - Hyperlink_write_only_cycles - Hyperlink_read_only_cycles; |
I do the same testing on DSP Internal memory address also and get the result(average of 100 times test result) below:
To | LL2 | SL2 | DDR3 | Remarks |
To local(REF) | ~19 ns | ~19 ns | ~25 ns |
|
To remote(Hyperlink) | ~4 ns | ~1 ns | ~22 ns |
|
So I would like to know that why the DDR3 for Local and hyperlink access latency is that close.
What’s the main contribution of the latency? The Terabus, DDR3 Chip or MSMC module?
Thanks a lot

CCS/CC2650MODA: Unable to connect with cc2650moda when programing
Part Number:CC2650MODA
Tool/software: Code Composer Studio
Hi, this is Edward, I want to program cc2650moda by using TI LanuchPad. However, it said that the debugger(Code Composer Studio) cannot detect the cc2650moda (error 242). I have already tried to program BOOSTXL-CC2650MA and it did work. Also I have tied 3v3,gnd,TDO,TDI,TCK,TMS,RST to the cc2650moda. I think these pins are enough to program cc2650moda, I have no idea why it can't work, can anyone help, appreciated.

LAUNCHXL-F28379D: Unable to download CPU2 flash
Part Number:LAUNCHXL-F28379D
I am attempting to load the flash on the LAUNCHXL-F28379D using the example projects blinky_dc_cpu01/02.
When built with configurations CPU1_RAM/CPU2_RAM respectively, I can load both cores (RAM) and both LEDs blink.
When I build with CPU1_FLASH_DEBUG/CPU2_FLASH, I can load CPU1 (LED flashes) but loading CPU2 hangs on "codestart: 0 of 4 at 0x80000", then fails with "Load Program Error: File: [mumble]: Load Failed" (that's the entire diagnostic). CPU1 continues to run undisturbed.
After it returns to the C perspective, the console window says:
------------------------------------------
C28xx_CPU2: Error occurred during flash operation: No core matches the pattern 'CPU1'
C28xx_CPU2: Error setting the GSxMSEL register for Flash operations
C28xx_CPU2: Error occurred during flash operation: Timed out waiting for target to halt while executing wr_pll.alg
C28xx_CPU2: Error writing the PLL values (Flash algorithm timed out). Operation cancelled.
C28xx_CPU2: Perform a debugger reset and execute the Boot-ROM code (click on the RESUME button in CCS debug window) before erasing/loading the Flash. If that does not help to perform a successful Flash erase/load, check the Reset cause (RESC) register, NMI shadow flag (NMISHDFLG) register and the Boot-ROM status register for further debug.
C28xx_CPU2: Error occurred during flash operation: No core matches the pattern 'CPU1'
C28xx_CPU2: File Loader: Memory write failed: Unknown error
C28xx_CPU2: GEL: File: C:\proj\workspace_v81\blinky_dc_cpu02\CPU2_FLASH\blinky_dc_cpu02.out: Load failed.
C28xx_CPU2: Error occurred during flash operation: No core matches the pattern 'CPU1'
C28xx_CPU2: Error setting the GSxMSEL register for Flash operations
------------------------------------------
I'm not sure how to "perform a debugger reset", since the Debug session closes. Also, I'm not sure where it's getting the string 'CPU1' from. Which is the primary error here?
This is very repeatable (~10 times so far). I've tried unchecking the "CPU1" boxes in the main tab of the Debug Configuration. The debug probe name says "C28xx_CPU2".
Where should I look next?

TMS320F28069: how many hardware factors decide the code executing speed
Part Number:TMS320F28069
Hi, all
My question is that what else hardware factors decide the code executing speed, besides the dominant frequency.
My test indicates that software is programmed on same chips (TMS320F28069) but different hardware board(both of the boards are in frequeny of 90Mhz) , the difference of speed is 30us.
The testing code is that only allow the timer 1 to interrupt, and in interrupted code, add test code shown in P.S., then test the GPIO58 signal.
P.S.
GpioDataRegs.GPBCLEAR.bit.GPIO58 = 1;
for( i= 0;i<50;i++)
{
__asm(" RPT #7 || NOP");
__asm(" RPT #7 || NOP");
__asm(" RPT #7 || NOP");

TPS92515HV: PWM dimming problem
Part Number:TPS92515HV
I did reference using TPS92515HVEVM-749 schematic.
It worked dim with fix IADJ and PWM 16KHz.
Because of flicker, I had to change the fsw frequency(580KHz -> 700KHz).
and It was working mistic.
When I was PWM Dim up, LED was more illuminated and stay normally.
I did change the PWM frequency 1KHz to 16KHz.
But 1~10KHz PWM frequency had made an Inductor's ringing noise.
I did Dim up, more illuminated's problem is made currently.
I want to know about that.
Below is my schematic
Vin was average 52V. Vled is below 46V. Iled is Max 0.8A.

CCS/MSP432P401R: How to use Stand-alone EnergyTrace without USB cable?
Part Number:MSP432P401R
Tool/software: Code Composer Studio
Hello,
I am working with MSP432P401R Launchpad to use stand-alone EnergyTrace feature in CCS.
I already used EnergyTrace several times in Debugging mode, so I am quite used to the feature.
The problem is I would like to use the stand-alone without USB cable.
I connected the launchpad with following several devices:
1. Power Supply 3.3V, 0.5A <-----> MSP432 external power supply pins.
- I connected Power supply machine to MSP432 for supplying power to the launchpad
- Simply blinky project is programmed in the launchpad, therefore, the LED starts blinking when the power supplies.
- Detailed picture is below
2. MSP432 launchpad's EnergyTrace part (upper part) <----- FTDI cable (mini USB b cable) -----> PC
- To send the EnergyTrace signal to CCS, I thought FDTI module is need for the connection.\
- I connected several pins:
MSP432 Isolation block ---------- FTDI cable
3V3 pin ----- VCC pin
GND pin ----- GND pin
TX pin ----- RX pin
RX pin ----- TX pin
- Also, I am aware of energyTrace's green LED which is on when XDS110 or EnergyTrace part is available.
- Detailed picture is below
I thought the configuration is fine for stand-alone mode, but CCS gave me an error window.
It stated me that the connection is not established properly.
Are there any additional things to do or anything wrong?
Thanks.
PS. CCS Version is 7.3.0.00019.
