Part Number:TMS320F28377D
Hi,
F28377-SPI has high speed mode activated by SpiaRegs.***.bit.HS_MODE,If I do not enable high speed mode, configure the low speed clock to 200M with ClkCfgRegs.LOSPCP.bit.LSPCLKDIV =0.
Can I configure SPIBRR to 4 or 9 for 40M or 20M, or must I enable High Speed Mode? When should the high speed mode be used, what is the highest clock frequency in high speed mode, 200M?
thank you！
Part Number:CC2564B
Hi,
We are using PAN1326B (CC2564B) Panasonic module with Bluetopia version 1.5R2 in one of the product. Bluetooh module interface with MSP430F2418 using 3 wire interface (Rx, TX and GND). during the weekend / continuous 4 to 5 days of testing with couple of device, we found few devices are BLE is not advertise. then we root case it with the debugger and identified, code is struck in the stack, its not at all coming out. So we decided to restart the device once in a 24 hrs; now we don't see this issue.
Since now we are doing the temperature cycling in the chamber -40 deg C to + 85 Deg C at 2 to 3 cycles and holding one hour for -40 and +85 Deg C, then continue to kept for +85 Deg C in 48 to 72 hrs. during this time BLE is not advertisement and triggering to reset the device. This reset leads for our device data log missing. Is there any way to check BLE health using the Bluetooth stack API's ?
Please conform any one has tested with -40 deg C to + 85 Deg C environment conditions ?
How do we address the BLE advertisement stop issue ? without resting the device.
Please suggest / recommend to handle the BLE error handling. what are the error conditions needs to take the actions ?
Note: PAN1326B module and MSP430F2418 microcontroller is used with BGA Package. Bluetooth debug UART signals are not brought out in the PCB; because of board density. As of now BT / BLE combo module we are using only BLE functionality.
Thanks,

Hi,

On Debugging the the code,i get the error in the following picture.
Anyone tell me how to rectify this problem.
Part Number:TPS54341
I am implementing a full bridge LLC resonant main circuit using a Resonant controller which has soft start capability i.e. during startup the operating frequency starts from 1MHz and rolls off till feedback takes over the control. For providing the required bias voltage of 15V, I am using TPS54341 controller based buck converter (500KHz) as auxiliary circuit for converting 28VDC input to 15VDC output.
Problem: When the resonant controller is ENABLE (after bias voltage (Vcc) is applied) , output of buck converter is falling from 15V and oscillating between 10V and 8V with low frequency defined by soft start capacitor. i.e. buck converter is found to be undergoing a hiccup, with time interval defined by soft start capacitor.
Steps Performed:
Please help me understand why I am facing issue only when I use voltage from Buck converter for powering resonant controller. Thanks.
I'm looking for suggestions on a part to regulate current to charge a 220mF EDLC from a LiSoCl2 battery. The current output of the battery can be as high as 50mA, but ideally lower, and the battery's open-circuit voltage is 3.6. I've seen the Energy Buffering for Long-Life Applications app note, which may be a possible solution, but perhaps there is something that is a little less complex. Thanks!

Hi，
I would like to ask, in the routine of the Piccolo processor, the function InitPieVectTable() for interrupt vector table initialization, where the source and destination addresses of the vector table need to add 3 (Source = Source + 3, Dest = Dest + 3; ) Where is the source of this plus 3? In contrast, the Delfino series processors do not need ‘plus 3’. Which one can tell you, thank you very much。
Part Number:AM3359
Hi
I have question regarding the MII connection between AM3359/AMIC110 and Ethernet PHY for Port 0.
In AMIC110 ICE (TMDXICE110) schematic, "AM_PHY1_LED1 (V2 of AMIC110)" and "AM_PHY1_RXCLK (V4 of AMIC110)" nets routed through Switch (U10).
whereas in AM3359 ICE (TMDSICE3359) schematic, "PR1_MII0_RXLINK_SPEED (V2 of AM3359)" and "PRUETH0_RXERR_COL_PROC (V3 of AM3359)" nets routed through Switch (U4).
Why in AMIC110 ICE pin V4 and in AM3359 ICE pin V3 is disconnected from PHY during boot?

Hi,
Please let me ask about LHR RPMIN setting. There is RPMIN SETTING value in Table 36, but I'm not sure how to calculate this value. For example, how can I calculate 0.75kohm? I tried to use 0.6V that is nominal sensor amplitude of 1.2Vpp but the result is 0.785kohm, not 0.75kohm.

Part Number:AM3703
Hi everybody ,
I need to redesign my AM3703CUS board and change NOR flash memory . I must boot and XIP in NOR , no OS on board .
I m using this page as reference --> processors.wiki.ti.com/index.php/AM3715/03_GPMC_Subsystem#16-bit_NOR_with_external_latch.C2.A0
so please some confirmation :
1- is AM3703 capable to boot from muxed and not muxed NOR if I use schematics as previous page ? anything to consider highlight in the two cases ?
2- after booting , only thing to consider in the two cases ( muxed or not ) is proper setting of GPMC ? anything to highlight ?
thank you

Part Number:SM320VC5421-EP
Hi,
I have been trying to find a list of all the DSP supported by latest version of Code Composer Studio (version 8.0 seems to be latest version)
The TI website has loads of documents but there seems to be missing a simple parametric search to have a full list of what DSP is supported by what version of CCS.
SM320VC5421 is only supported by CCS 3.0 (obsolete version unless you want to use WinXP)
So a full parametric search with a more exhaustive list of DSP parameters would help.
If the parametric search could have CSS version and also the package type of the DSP device (BGA, QFP..etc...), this would help greatly in finding alternative to the VC5421 DSP a lot faster.
Any help would be greatly appreciated.
Best Regards

Our customer wants to perform any time a rollback to the previous Image. Even though a new update was successful and committed, he wants to have the possibility to roll back to the last version later on.
Our approach:
Before an OTA update starts, create a copy of the actual mculfashimg.bin (read mculfashimg.bin -> write in mcuflsasimgcopy.bin) . Then perform a regular update.
If at some time a custom rollback is necessary, the copy of the mcu binary will be read back to the mcuflashimg.bin (read mculfashimgcopy.bin -> write in mcuflsasimg.bin)
Both file are created with failsafe mode. This means, a bigger SFLASH has to be considered. But do you think, that this approach is feasible?
Thanks for your support.

Hi TI Support team,
We are using AM3358 embedded linux using phy KSZ8081. We are using the speed of 100mbps in our product.
We see that when storm attack like TCP, UDP or ethernet storm is performed, we are not able to rate limit the packets coming to the device.
We also have the patch below for enabling coalescing including multicast broadcast limit.
https://patchwork.kernel.org/patch/4512111/
This patch seem to work in 10Mbps mode but not in 100Mbps mode.
Please help us in resolving the storm attacks in 100Mbps mode of operation by providing us a method for rate limiting.
Thanks.
With Regards,

Part Number:TL432B
Hi, I'm using TL432B-Q1 in my project. I'm doing worst-case-condition-analysis.
Per TL432BQDBZRQ1 datasheet, it defined many items, eg. reference voltage Vref and deviation of reference voltage over full temperature range VI(dev)...
The system will do calibration at the factory. The operating temperature of the product is -40oC to +125oC. The application is same as Figure 3 in datasheet with R1=1k, R2=3.01k, 5V input.
Which item can be eliminated by doing the calibration?
Which item should be taken into account?
Part Number:MSP430FR6047
Dear Sir,
Our water meter project is based on CCS project UltrasonicWaterFR6047_01_40_00_01 which uses USSLib_01_40_00_06.
As a start point we used default configuration settings in USS_userConfig.c where
.triggerConfig = USS_Triger_Configuration_Software_Trigger;
and everything goes well.
We also registered some callbacks:
USS_registerSAPHInterruptCallback(USS_SAPH_Interrupt_SEQDN, SeqDoneCallback);
USS_registerSDHSInterruptCallback(USS_SDHS_Interrupt_ACQDONE, AcqDoneCallback);
which are invoked from library also.
But when we changed USSLib setting to start measurement from TA0 CCR2:
.triggerConfig =USS_Triger_Configuration_External_Trigger1;
then we met next problems:
1. We found that USS Xtal is not started after calling USSLibGUIApp_Init so we added next code:
HspllUssInitParam.oscillatorType = HSPLL_XTAL_GATING_COUNTER_LENGTH_4096;
HspllUssInitParam.xtlOutput = HSPLL_XTAL_OUTPUT_DISABLE;
HspllUssInitParam.oscillatorEnable = HSPLL_XTAL_ENABLE;
HSPLL_xtalInit(HSPLL_BASE, &HspllUssInitParam);
2. Our registered callbacks are note invoked untill we added next code:
SAPH_enableInterrupt(SAPH_BASE, SAPH_ACQUISITION_SEQUENCER_DONE_INTERRUPT);
SDHS_enableInterrupt(SDHS_BASE, SDHS_ACQUISITION_DONE_INTERRUPT);
So we have next questions:
1. Is there another variant of CCS project UltrasonicWaterFR6047_01_40_00_01 which triggers USSLib by TA0 CCR2 or RTC, not by Software?
2. If we trigger USSLib by TA0 CCR2 what else we should configure by ourselves?
3. As we found callback on USS_SDHS_Interrupt_ACQDONE invokes two times on one measurement trigger. Is it because of two measurements in sequence?
.sequenceSelection = USS_measurement_capture_sequence_ch0_ch1;
4. What callback should we use to know that measurements are finished and we can invoke USS_runAlgorithmsFixedPoint function? As for now we use callback on USS_SDHS_Interrupt_ACQDONE.
Thank You very much for You answers.
