Part Number: BQ24773
Hello
Previously, I worked with BQ24770 and now I need to work with BQ24773.
I identified only one difference between them. The BQ24773 needs 1.8V connected via a 10K resistor on the SDA and SCL pins, while the BQ24770 needs 3.3V.
Could I keep 3.3V on the BQ24773 too?
Another point, the PROCHOT Pin is also connected with the 10K resistor at 3.3V, could I connect the PROCHOT Pin at 1.8V?
I would like to use only one voltage regulator , 1.8V or 3.3V.
Thank you

Part Number: TMUX1136
Hi folks -
I'm looking at TMUX1136 for a low-current power switching application, ~10mA. Can I connect the switches in parallel to lower the effective RON in the system? 1 ohm is nice, but 0.5 ohm is twice as nice!
There won't be signal here, so no concern with distortion etc.
Tiny Package size and 1.08V operation are critical features.
Thanks much!
Part Number: DRV8323
When the DRV8323 ENABLE pin is brought high, for the first time, what state is it in (brake, registers and FETs)?
What state is the DRV8323 left in when the ENABLE pin looses power (brake, registers and FETs)?
When the DRV8323 ENABLE pin is brought high, after loosing power, what state is it in (brake, registers and FETs)?
Are the above states dependent on whether VM is at system voltage?
Should the ENABLE pin circuitry be pulled low with a pull-down resistor?
What happens to the register values when the ENABLE pin looses power?
The linked thread has the schematic layout.

Hi,
SDK v3.10.00.15, CCS v9.0.1
I have made an OAD transfer of an application user on a custom board. The flash size has been adapted to the new one (8Mbyte). Btootl show a valid OAD transfer. Only the software version has changed between the old and new app user. But the BIM doesn't start the new application user after reset.
All metadata read with the function "static int8_t isLastMetaData(uint8_t flashPageNum)" show invalid image ID like random values or full 0xFF. The image ID is the default (OAD IMG ).
Maybe the start address of the write and read metadata are not the same in BIM and APPLICATION ? I don' know where exactly are written the metadata of the application user transfer by OAD.
Best regards,
Vincent
Part Number: TCI6638K2K
We want to handle AIF2 AT event at ARM Corepac which is running linux OS. From the TCI6638K2K document SPRS836G (page 103) we are seeing AIF_ATEVT[0-7] mapped to system event 408-415. Now how do we register an interrupt handler for these events at linux. Any pointers on how this is done or an example code will be really helpful.

Part Number: PGA411-Q1
Hello team,
I have two questions about PGA411-Q1:
1. Customer report a very slow change from maximum AOUT to minimum AOUT (see ch3 purple line) while in datasheet it should be very fast, do you have any insights on it?
2. There is a sharp drop of the angle read from SPI when the rotate speed is between 4000-5000RPM, while AOUT angle is right.
Thanks

Part Number: DRA744
Hi everybody ,
I m in Android 4.3 and using a WIFI module attached via SDIO signals .
WIFI module can work @ 3.3 V or 1.8V SDIO IO signals , and I am on eMMC1 .
now using signals @ 3.3V everything is fine . if I use 1.8V level ( with proper settings etc ) module is not working .
what I noticed using a scope --> no signal or bus activity by DRA744 at all , all signals are stuck if IO are set @ 1.8V
I noticed in TRM you need to start @ 3.3 V on IO on SDcard ( it is in table 25-2 ) : is this needed also for SDIO ? ( in the TRM it seems not ..)
please where am I wrong ?
best regards

Part Number: CC1310

HI,
I am working with two CC1310 sub 1 GHz board. Programmed such a way that,
Everything works fine when both master and slave are in debug mode( no stepping, no breakpoints).
But anyone side is not in debug mode, its receive does not work properly, it's unstable, most of the times it doesn't work.
My code for receive in the master with infinite waiting is,
int receive()
{
int status = 0;
RF_Params rfParams;
RF_Handle rfHandle;
RF_Object rfObject;
RF_Params_init(&rfParams);
if (RFQueue_defineQueue(&dataQueue, rxDataEntryBuffer, sizeof(rxDataEntryBuffer), NUM_DATA_ENTRIES, MAX_LENGTH + NUM_APPENDED_BYTES)) {
/* Failed to allocate space for all data entries */
while (1);
}
RF_cmdPropRadioDivSetup.centerFreq = 0x0YYY;
RF_cmdPropRx.pQueue = &dataQueue; /* Set the Data Entity queue for received data */
RF_cmdPropRx.rxConf.bAutoFlushIgnored = 1; /* Discard ignored packets from Rx queue */
RF_cmdPropRx.rxConf.bAutoFlushCrcErr = 1; /* Discard packets with CRC error from Rx queue */
RF_cmdPropRx.maxPktLen = PAYLOAD_SIZE; /* Implement packet length filtering to avoid PROP_ERROR_RXBUF */
RF_cmdPropRx.pktConf.bRepeatOk = 0;
RF_cmdPropRx.pktConf.bRepeatNok = 0;
RF_cmdPropRx.syncWord = 0xXXXXXXXX;
RF_cmdFs.frequency = 0x0YYY;
rfHandle = RF_open(&rfObject, &RF_prop, (RF_RadioSetup*) &RF_cmdPropRadioDivSetup, &rfParams);
RF_CmdHandle rx_cmd_handle = RF_runCmd(rfHandle, (RF_Op*) &RF_cmdFs, RF_PriorityNormal, NULL, 0);
RF_EventMask result = RF_runCmd(rfHandle, (RF_Op*) &RF_cmdPropRx, RF_PriorityNormal, NULL, IRQ_RX_ENTRY_DONE);
if((result == RF_EventLastCmdDone) && (RF_cmdPropRx.status == PROP_DONE_OK))
status = 1;
RF_close(rfHandle);
return status;
}
Code for receive in slave side(with a 10 sec timeout) is
uint64_t Receive()
{
uint64_t status = 0;
RF_Handle rxrfHandle;
RF_Params rfParams;
RF_Object rfObject;
RF_Params_init(&rfParams);
if (RFQueue_defineQueue(&dataQueue, rxDataEntryBuffer, sizeof(rxDataEntryBuffer), NUM_DATA_ENTRIES, MAX_LENGTH + NUM_APPENDED_BYTES))
{
while (1);
}

RF_cmdPropRx.pQueue = &dataQueue; /* Set the Data Entity queue for received data */
RF_cmdPropRx.rxConf.bAutoFlushIgnored = 1; /* Discard ignored packets from Rx queue */
RF_cmdPropRx.rxConf.bAutoFlushCrcErr = 1; /* Discard packets with CRC error from Rx queue */
RF_cmdPropRx.maxPktLen = PAYLOAD_SIZE; /* Implement packet length filtering to avoid PROP_ERROR_RXBUF */
RF_cmdPropRx.pktConf.bRepeatOk = 0;
RF_cmdPropRx.pktConf.bRepeatNok = 0;
RF_cmdPropRx.endTrigger.triggerType = TRIG_REL_START;
RF_cmdPropRx.endTrigger.pastTrig = 1;
RF_cmdPropRx.endTime = (uint32_t)(4*10000000);
RF_cmdPropRx.syncWord = 0xXXXXXXXX;
RF_cmdFs.frequency = 0x0YYY;
RF_cmdPropRadioDivSetup.centerFreq = 0x0YYY;
rxrfHandle = RF_open(&rfObject, &RF_prop, (RF_RadioSetup*) &RF_cmdPropRadioDivSetup, &rfParams);
RF_CmdHandle rx_cmd_handle = RF_runCmd(rxrfHandle, (RF_Op*) &RF_cmdFs, RF_PriorityNormal, NULL, 0);
RF_EventMask result = RF_runCmd(rxrfHandle, (RF_Op*) &RF_cmdPropRx, RF_PriorityNormal, NULL/*&callback*/, IRQ_RX_ENTRY_DONE);
// RF_Stat stat = RF_cancelCmd(rxrfHandle, RF_CMDHANDLE_FLUSH_ALL, 0);

Dear all
I have some questions about this bq7693003 device, please help me to reply, Thanks a lot.
1. What is the effect of voltage and temperature on ADC cell voltage accuracy? Is the higher temperature,the higher the accuracy ?
2. Please show me all factors that effect the ADC cell voltage accuracy, It is very important. Thanks.
3. The Lead/ball finish of bq7693003DBTR device is NiPdAu, Does the pins is only plating bottom ? On both sides of the pins is plating ?
4. For SMT, could you share me the temperature curve,and share me the matters need attention for prevent cold solder joint .

Part Number: AM3352
Dear Sitara champs,
Consider the following diagram of a use case using the dual port switch on the AM3352.
There's an AM3352 Sitara board with a WLAN/BT module on it. There's another board we'll call the other module which has a microprocessor on it running an Ethernet stack. The question is, can we do the following?
Can the other module access both the WLAN on the Sitara board *and* access the network camera? If so, how would we go about setting this up from the Linux side of things running on Sitara? Does the AM3352 assign IP addresses to the other module and the camera?
Thanks
Part Number: PROCESSOR-SDK-AM335X
We used BeagleBone black for development and were able to load SPL and uboot via UART. When I try to load that same SPL via UART to our new hardware. it freezes (ie crashes). I connected a Blackhawk JTAG to our board and used Code Composer Studio to step through the code. Seems to crash when setting up I2C clocks? I removed a lot of the init code under */board/ti/am335x/board.c including . It still crashes.
I build uboot using
make -j 2 -C $(UBOOT_SOURCE_DIR) am335x_evm_config
make -j 2 -C $(UBOOT_SOURCE_DIR) CROSS_COMPILE=$(CROSS_COMPILE) CONFIG_MKIMAGE_DTC_PATH=$(UBOOT_SOURCE_DIR)/scripts/dtc/dtc
I don't understand why the default SPL build for Beaglebone would crash. Even if the peripherals aren't connected it shouldn't crash.
When I just have it pinmux for UART0 and setup our DDR2 timing, it still crashes.
Is there something i should be doing differently? Is there someway to debug the reason for crashing? Enabling debug printing from within SPL code?
Thanks for any help!
Part Number: CC3220SF-LAUNCHXL
Tool/software: Code Composer Studio
Hi,
in my current project I work with the CC3220SF-LAUNCHXL and parts of this project involves obtaining power measurements during run-time of my program. For this, I recently purchased the standalone XDS110 Debug Probe (TMDSEMU110-U) together with the XDS110 EnergyTrace HDR (TMDSEMU110-ETH). To get started, I followed the instructions from the Application Report: CC3135, CC3235x SimpleLink Wi-Fi Internet-on-a chip Networking Subsystem Power Management (SWRA594) and I managed to get power measurements using the Power Measurement Example and EnergyTrace.
Next, I would like to debug my custom program using the standalone debug probe, so I can use EnergyTrace while in debug mode. For this, I connected the 20-pin debug cable to the board (J8) using the TI 20-pin to ARM Cortex 10-pin converter adapter and I connected the 14-pin auxiliary cable to the board (J7) as well. Also I removed all jumpers from the jumper block, OPAMP and LED. In the end the setup looked like this:
In CCS, I work with a modified version of the Power Measurement Example, before I started any debug session I first went to Target Configuration and made sure that the XDS110 Debug Probe supplies power to the board. My final configuration looked like this:
Next, I hit "Test Connection" and I always get the error mentioned in the title: 'SC_ERR_PATH_BROKEN'
Am I missing something simple here? These are things I already tried:
Here are more details regarding my setup:
So in the end my question boils down to, why do I always get the error 'SC_ERR_PATH_BROKEN' and is there a way to fix it? My goal is to use EnergyTrace while debugging my program. Any help on this is greatly appreciated.
Thanks in advance,
Sebastian
