CCS/DLP3010: Firmware size .bin for DLP3010 generated by CCS is not same as the default .img
Part Number: DLP3010
Tool/software: Code Composer Studio
Hello,
I want to update the firmware for DLP3010, but it doesn't work, and I found that the size of .bin (60 kilo byte) is totally different size with the default .img file (1200 kilo byte) as below.
I generated .bin which was generated by converting .hex to .bin at Build setting of CCS 9.2.0 using (mkhex4bin.exe etc), but it doesn't have any binary data when I opened it nor didn't it work after uploading the .bin.
1. Is there any problem in that the size of .bin is different from default .img file ?
2. how can I create a output file .img or .bin to update firmware?

LMK01801: Max and Min CLKin duty cycle
Part Number: LMK01801
The LMK01801 CLKin0 and CLKin1 are specified as analog input, but also specified as duty cycle as 50% without min and max limit.
What is the min and max duty cycle allowed for both of these CLKin by design?
Can these CLKin accept 30% LVCMOS33 duty cycle input ?

DRV8711EVM: Can we use Labview to control DRV8711EVM?
Part Number: DRV8711EVM
Hi Ti,
Can I use other programming software, like Labview, to communicate with this module? We want to synchronize the motor with our system. GUI seems unable to do that.
Best regards,
Siyuan

TPS731: Acceptable to force OUT pin to 4.2V?
Part Number: TPS731
I'm analyzing a potential fault condition where a 4.2 V stiff supply gets applied to the OUT pin of TPS731. The regulation FB network will be set for around 3.7 V. IN is at 5V (USB).
Is this safe for the part?
Will there be appreciable leakage current from OUT to IN?

TMS320F28379D: F2837x high resolution PWM
Part Number: TMS320F28379D
Hi
I have a F2837x project that sets PWM1 and PWM2 as high resolution PWMs.
At the very beginning the program calls HRPwmCalibration() function and when
it enters SFO() it doesn't return from the function.
I have checked TI's high resolution PWM example and couldn't find any clue.
I have uploaded the project as below.

TPS65263-1Q1: SYNC POLARITY
Part Number: TPS65263-1Q1
I have a 67 % DC square wave, 1 Mhz, wich i want this TPSxx to syncronize to. This is exactly the switch node voltage of another buck, cascaded on the out of CH1 of TPS65263-1Q1.
Datasheet explains that:
-the active sync edge for TPS is the falling one.
-CH1 is 180° w respect to other channels
-on page 22 the period "....At the end of every clock cycle, the low-side MOSFET sourcing current is compared to the internally set low-side sourcing current limit. ...." enforces the idea that the transition to 'ON' state will take place at cycle start, thus at sync pulse falling edge.....
BUT
-Figure 63 on page 36 shows real case scoped signals. Polarity of signals here seem counterdicting explainations; Anyway CH1 here transition high a little while after the sync falling edge. So, if confirmed, a little inverting buffer may do.
Question:
1) what am i missing? Is it that CH1 is 0°, and CH2 & CH3 are 180° rotated, instead? This would explain everything.
2) Apart from the reasons, will CH1 always have it's rising edge within a reasonably little time from sync fall, for every TPS DUTY CYCLE?
Thanks, Francesco

We are looking at using the TRF7970A in a new design. I see that it is listed as an active component but wanted to see if there is any possibility of it going EOL or being replaced in the near future. From the dates on the datasheet it appears to have been around 8 years since the part originally released.

LAUNCHXL-CC26X2R1: Memory corruption occurs when using high ZDSECMGR_TC_DEVICE_MAX value
Part Number: LAUNCHXL-CC26X2R1
Hi,
I'm currently testing the CC26X2R1 with zigbee2mqtt and think I've stumbled upon a memory corruption issue.
I currently have a stable firmware which uses ZDSECMGR_TC_DEVICE_MAX=100, however I want to increase this further (to e.g. 200).
Jason provided me the device table sizes mentioned below and a memory calculation based on https://e2e.ti.com/support/wireless-connectivity/zigbee-and-thread/f/158/p/834603/3105789#3105789 indicated that this should be possible. Memory calculation including device table sizes:
Total amount of NV = 0x4000 bytes = 16384 bytes NWK_MAX_DEVICE_LIST = 50 * 23 bytes = 1150 bytes ZDSECMGR_TC_DEVICE_MAX = 200 * 27 bytes = 5400 bytes NWK_MAX_ADDRESSES = 257 * 19 bytes = 4883 bytes ((NWK_MAX_DEVICE_LIST 1) NWK_MAX_BINDING_ENTRIES (ZDSECMGR_TC_DEVICE_MAX 5)) MAX_NEIGHBOR_ENTRIES = 20 * 20 bytes = 400 bytes MAX_RTG_ENTRIES = 100 * 7 bytes = 700 bytes MAX_RTG_SRC_ENTRIES = 200 * 6 bytes = 1200 bytes Others = - 2300 bytes Remaining = 351 bytes
For the firmware which runs stable I use the settings below.
#define INCLUDE_REVISION_INFORMATION #define MT_SYS_KEY_MANAGEMENT 1 #define FEATURE_NVEXID 1 #undef NWK_MAX_BINDING_ENTRIES #define NWK_MAX_BINDING_ENTRIES 1 #undef APS_MAX_GROUPS #define APS_MAX_GROUPS 1 #define MULTICAST_ENABLED FALSE #define MAX_BCAST 30 #define CONCENTRATOR_ENABLE TRUE #define CONCENTRATOR_DISCOVERY_TIME 120 #define CONCENTRATOR_ROUTE_CACHE TRUE #define MAX_RTG_SRC_ENTRIES 200 #define SRC_RTG_EXPIRY_TIME 255 #define NWK_MAX_DEVICE_LIST 50 #define ZDSECMGR_TC_DEVICE_MAX 100 #define MAX_NEIGHBOR_ENTRIES 20 #define MAX_RTG_ENTRIES 100
However when increasing the ZDSECMGR_TC_DEVICE_MAX to greater values, e.g. 150, I get very weird behaviour. E.g. after a device joined I cannot get a response to a node descriptor request (seems that it doesn't receive any messages at all).
I think I found an easy way to detect that memory corruption occurs. Below are 2 logs of writing a NV item using Z-tool:
ZDSECMGR_TC_DEVICE_MAX=100
<TX>07:41:28.7 COM12 SYS_OSAL_NV_ITEM_INIT (0x2107)

ZDSECMGR_TC_DEVICE_MAX=150
<TX>07:31:51.03 COM12 SYS_OSAL_NV_ITEM_INIT (0x2107)

Value: U (0x55)
<RX>07:32:19.58 COM12 SYS_OSAL_NV_WRITE_SRSP (0x6109)
Status: INVALID_PARAMETER (0x2)
As can been seen, the OSAL_NV_WRITE fails on the firmware with ZDSECMGR_TC_DEVICE_MAX=150 (with a very strange error???) while it succeeds on the firmware with ZDSECMGR_TC_DEVICE_MAX=100. I've included the full Z-Tool log for both in the attachment, using this it should be possible to reproduce the issue.(Please visit the site to view this file)(Please visit the site to view this file)

CCS/TMS320F28379D: High speed simultaneous sampling on multiple ADC modules
Part Number: TMS320F28379D
Tool/software: Code Composer Studio
Hello - I am trying to do high speed current sampling using the ADC modules. I assigned ADCINAO, ADCINB0 and ADCINC0 to my signals and here is the code that I used for ADC setup:
AdcaRegs.ADCSOC0CTL.bit.CHSEL = 0
AdcaRegs.ADCSOC0CTL.bit.ACQPS = 19
AdcaRegs.ADCSOC0CTL.bit.TRIGSEL = 5;
AdcbRegs.ADCSOC0CTL.bit.CHSEL = 0;
AdcbRegs.ADCSOC0CTL.bit.ACQPS = 19;
AdcbRegs.ADCSOC0CTL.bit.TRIGSEL = 5;
AdccRegs.ADCSOC0CTL.bit.CHSEL = 2;
AdccRegs.ADCSOC0CTL.bit.ACQPS = 19;
AdccRegs.ADCSOC0CTL.bit.TRIGSEL = 5;
However, I am not able to read anything from the corresponding result registers. I guess my trigger source has not been set properly can you please let me know how I need to setup my trigger source? (in this case is ePWM1 SOCB? This is how I did:
EPwm1Regs.ETSEL.bit.SOCBEN = 1;
EPwm1Regs.ETSEL.bit.SOCBSEL = 0x1;
Also if I get this working, what would be the fastest rate to read digital values? Can I get to 1MHz reading rate?
