TMS320LF2407A: Boundary scan?

$
0
0

Part Number: TMS320LF2407A

The datasheet states “The x240xA DSPs do not include boundary scan. The scan chain of these devices is useful for emulation function only.”

Does this mean that Boundary Scan testing of downstream devices in the JTAG chain can’t be done through the tms320lf2407a JTAG interface?

Since it does not support boundary scan, I guess it would need a bypass mode in order to do this. Does it have this bypass mode?

Part Number: LM5050-1

Hi Guys

Our customer is using our LM5050, their system: typical 48V, MAX 54Vout; But there will be a surge voltage ~100V about 10us; not sure accurate value; But they are concern our datasheet:

Our device exposure to max conditions for extended periods may affect device. So typically how much voltage value do you test to prove this explanation? 110V for 1us? or some other value for several seconds? Customer want to design a Absorption energy protection circuit. So need our this test data. if you have no, do you know how much voltage will affect our device?

Thanks

TPS650861: Scaling output voltage of BUCK2 with external resistors

$

Part Number: TPS650861

Hello,

I'm testing TPS650861 for our new project.

I need to get 3 voltages from BUCK1, 2 and 6:

- Fixed 3,3V

- Fixed 5V

- Digitally regulated 2,5...5V

My idea is to get:

1. Fixed 3,3V from BUCK6 - because of internal VTT LDO feedback, it's output cannot be higher then 3,6V so this is the option for 3,3V.

2. Fixed 5V from BUCK1 - using the Ext FB option with external resistors

Question: Am I correct that when Ext FB option is selected, then there is no possibility to change the output voltage using VID reg. value?

3. Regulated 2,5...5V from BUCK2 - I added a serial resistors on the FBVOUT2 and I measured that there is 8,2uA current flowing into the feedback pin. From there I calculated a serial resistor of 174k and that gives me the desired voltage range.

Question: My question is about the structure of the FBVOUT2 input. Is there a simple resistor divider at that input connected to a comparator? Is my solution OK or may it ruin some feedback characteristics??? Can you tall me about the input structure of that pin so that I would know what I'm doing?

I really hope this will work as this PMIC would be perfect for our system.

Kind Regards,

Jacek Renkas

Part Number: CC3220MODA

Hi

 

Our customer has question of APP_EVENT DISCONNECT.

 

I attach logs.

(Please visit the site to view this file)

 

The both logs offer "Device disconnected from the AP on an ERROR".
 

In left logs, it succeeds to reset and reboot the system using platform reset.

In right logs, it repeats "Device disconnected from the AP on an ERROR" with 204 and 208 alternately after using platform reset.

 

I don't know why there are differences between upper two cases.

 

Could it be possible that there are differences in behavior after platform reset depending on the connecting router?

 

If yes, could you tell me the router function that will cause to above differences in behavior?

 

BestRegards

Hello All

I have some problem with developmnet and debugging application where the CM control USB Periphery.

 I can not to see the registers of USB on the Cortex_M4_0 side. I can see this one only on the C28xx_CPU1 side.

Besause it is appiared only on the C28xx_CPU1 side, on the Cortex_M4_0 side it is absent.(For example CANA and CANB registers I can abserve on the both sides)

So statement  HWREGB(ui32Base + USB_O_GPCS) = USB_GPCS_DEVMODOTG | USB_GPCS_DEVMOD,

which is fulfilled on the Cortex_M4_0 side does not make any effect to the registers. Or at least I do not observe any changing on the  C28xx_CPU1 side.

The Clock gating is configured properly  on the both sides and PALLOCATE0 register configured to allocate USB_A to CM side.

Can somebody help me ?

Best regards

Part Number: INA286

Hi Guys

Our customer will use our INA286  as high side current sense. Typical common mode voltage is 48V. But we have some questions:

1. If we power off our device, but the main power voltage is high voltage 48V. So at this no power supply conditions, do you think whether it will damage our device when power up INA286 or operation?

2. If we have no power supply, how much quiescent current will our device have? 900uA? 500uA? or lower?

Thanks

Part Number: TMS320F280049

Hi expert,

I am tring to lock F280049 with the provided asm file and cmd file but it seems goes to wrong location. Here is the asm file I modified and memory content.

It seems not to the right position, what happens here?

Attached the cmd and asm here.

CMD:

/* this linker command file is to be included if user wants to use the DCSM
 * feature on the device DCSM  means Dual Zone Code Security Module. This
 * linker command file works as an addendum ot the already existing Flash/RAM
 * linker command file that the project has.
 * The sections in the *_ZoneSelectBlock.asm source file is linked as per the
 * commands given in the file NOTE - please note fill=0xFFFF, this helps if
 * users include this file in the project by mistake and doesn't provide the
 * needed proper *_ZoneSelectBlock.asm sources.
 * Please refer to the Blinky DCSM example for proper usage of this.
 *
 * Once users are confident t`hat they want to program the passwords in OTP, the
 * DSECT section type can be removed.

;; FILE:   f28004x_dcsm_z1otp.asm
;;
;; TITLE:  Dual Code Security Module Zone 1 OTP
;;
;; DESCRIPTION:
;;
;;         This file is used to specify Z1 DCSM OTP and zone select block
;;         values to program.
;;
;;         In addition, the 60 reserved values after the zone select block
;;         are all programmed to 0x0000 as well.
;;
;; !!IMPORTANT!! The below memory sections are mapped to OTP (one-time
;; programmable) memory with the *dcsm_lnk.cmd linker command file. In order
;; to program the below memory sections, user should uncomment the .long words
;; of each section and change the value to what is desired. Additionally, the
;; corresponding section of *dcsm_lnk.cmd should no longer be labelled as a
;; dummy section. Remove ", type = DSECT" in SECTIONS from the memory section
;; that is being programmed.
;;
;;
;; !!IMPORTANT!! The "bx_dcsm_otp_z1_linkpointer" section contains the
;; Z1 LINKPOINTER which determines the location of the Z1 Zone Select block.
;; If the LINKPOINTER is changed, then the "bx_dcsm_zsel_z1_linkpointer"
;; section in the *_dcsm_lnk.cmd command linker file must also change to an
;; address decoded from the value specified in the Z1-LINKPOINTER location.
;;
;;
;; The "bx_dcsm_zsel_z1" section contains the actual Z1 Zone Select Block
;; values that will be linked and programmed into to the DCSM Z1 OTP Zone
;; Select block in OTP.
;; These values must be known in order to unlock the CSM module.
;;
;; It is recommended that all values be left as 0xFFFFFFFF during code
;; development.  Values of 0xFFFFFFFF do not activate code security and dummy
;; reads of the Z1 DCSM PWL registers is all that is required to unlock the
;; CSM. When code development is complete, modify values to activate the
;; code security module.
;;
;; ******************************WARNING***************************************
;; It is recommended not to program 0xFFFFFFFF to user OTP locations, if users
;; intend to comeback and re-program any of the bits to '0' in future. If user
;; programs 0xFFFFFFFF to any of the OTP locations then the ECC locations would
;; get programmed to a non erased state and users won't be able to comeback
;; and re-program the OTP location to another value. Please refer to DCSM
;; chapter of device TRM for more details on ECC for the locations in DCSM.
;;
;; Hence TI ships this example commenting out the initialization of all the
;; below locations.

ADC -> uController +DAC or MCU -> MCU?

$
0
0

We are considering adding some optical isolation barrier for some new products.  The Analog isolation chips available on the market do not provide 
enough isolation for what we need.

As of now, the design options we have are:
1. PWM
2. ADC -> uController +DAC
3. MCU -MCU

The PWM option seems like a very good option due its lower cost and complexity. However, we are not sure about the performance. (linearity and bandwidth)

If we were to go one level higher in performance we were thinking of digitizing the signal and reconstructing after the isolation barrier. For that, however, 
it seems like we'd have to decide if we''d go with a more granular approach involving ADCs or a more "off the shelf" option with MCUs.

We'd love to have >=1MSPS and 14 to 16 bits digitization. For reconstruction of the waveform, I'd hope to have the same sampling rate and similar resolution.
Could you please comment on the complexities involved in choosing one way or another? Would there be substantial savings either in terms of development time 
and/or components depending on which route we'd select?

Chemical fuse on a 14S1P batteries BMS

Hi there,

I'm designing a BMS based on yours TIDA-00792, which use the BQ78350DBTR-R1, BQ7694000DBTR and BQ76200PWR devices. My topology is a 14S1P.

I would like to add a secondary protection; I mean a chemical fuse (you know a fuse with a third leg capable to trigger its fuse via an internal heater).

I know that the device BQ7718 is designed just for this requirement; BUT BEFORE to add 3 of them on my design:

--> I would like to know if there are some way to add this feature with the BQ78350DBTR-R1 or BQ7694000DBTR. I'm trying to save this BQ7718 devices on my design.

Thanks a lot

Part Number: OPA858DSGEVM

Hi, an urgent help request.

We have purchased an Evaluation Module for OPA858 amplifier, OPA858DSGEVM several days ago, and have tried

the module to test it for our OPA858 pulse amplification circuit design for our product.

However, the module doens not work at all. we have found the circuit uses R3 zero ohm resistor connected

in parallel with the differential input terminal to the ground. That means resistor R3 shorts out the RF input signalm and

consequently the module doe not output any siganl waveform to eh oscilloscope at the output connector.

Why did you short the input terrminal by R3. How can we test the moduel? Please explain the situation. Is it an mistake?

Do we have to remove the resistor R3, which is also very small and thus even very difficult to remove it.

Please give me immediate answer. I don't understandwhy this happened.

Regards,

Ki-Chang Lee

P.S. My collegue Iksoo Choi already have asked this matter to you on Friday. But still he did not get answer from TI.

I built a board exactly as the TPS23754EVM-383, but the output is only 2.3V and unstable.

The VC voltage is around 11V, but the GATE and GAT2 are not driving the FETs( 0.2V on these).

Where do I need to look for diagnose , please !

Tool/software: Code Composer Studio

Hello All

I have some problem with developmnet and debugging application where the CM control USB Periphery.

 I can not to see the registers of USB on the Cortex_M4_0 side. I can see this one only on the C28xx_CPU1 side.

Besause it is appiared only on the C28xx_CPU1 side, on the Cortex_M4_0 side it is absent.(For example CANA and CANB registers I can abserve on the both sides)

So statement  HWREGB(ui32Base + USB_O_GPCS) = USB_GPCS_DEVMODOTG | USB_GPCS_DEVMOD,

which is fulfilled on the Cortex_M4_0 side does not make any effect to the registers. Or at least I do not observe any changing on the  C28xx_CPU1 side.

The Clock gating is configured on the both sides and PALLOCATE0 register configured to allocate USB_A to CM side.

Can somebody help me?

Part Number: MSP430F5529

Hello,

I am trying to implement a millisecond counter that can operate for 24 hours without overflow. The purpose is to create time stamps for event log with distinguishable milliseconds. No external clock source available.

RTC in 32-bit counter mode seems to be the only option, but I couldn't find any examples on how to set it up. Can you please share some or suggesto some other way to solve the problem?

Regards,

Hi,

My customer requires TI to provide the Isw of average switch current limit at Vout=5V.  I refered Figure.1,  but it's shows output current ability.  What is the exact value of the current limit at Vout=5V?
