TMS320F280049: Unexpected GPIO firing on F280049 during EMC test
Part Number:TMS320F280049
Merry Christmas experts,
Customer found unexpected GPIO26 toggling on 100pin F280049 during EMC test, even without any change on GPIO26's "data", "clear", "set" or "toggle" register.
They have inserted some code to check GPADAT.bit.GPIO26 and this bit is changed even without intended change. Finally, they found "GpioDataRegs.GPADAT.bit.GPIO25 = 0" in ISR caused this problem, after they changed to "GpioDataRegs.GPACLEAR.bit.GPIO25 = 1", GPIO26 will not have any problem any more.
Could help me with any explanations or suggestions?
Thanks
Sheldon

LM48511: Calculate Gain
Part Number:LM48511
Hi Sirs,
Sorry to bother you.
1. We would like check does TI have Class D AMP include stereo 8ohm/2w/5v? because i couldn't search on TI web side
2. We use LM48511 on Mono Mode design with 2W, Schematic as below
So, based on datasheet, the gain should be equal AVD= 2*Rf/Rin, right?
If we use dual single ended input design, how to calculate Gain? same AVD= 2*Rf/Rin
3. Could you help double check our schematic?

Hi
I want to enable smp in my rtos project based on evmAM572x, but some building errors occurred after i modified some codes in main.cfg.

BIOS.smpEnabled = true;
var Core = xdc.useModule('ti.sysbios.family.arm.a15.smp.Core');
Core.useSkernelCmd = false; /* Set to false if running in CCS and using gel files to wake-up secondary cores */
Core.numCores = 2;

TLC555: Threshold voltage level with temperature dependency
Part Number:TLC555
Hi,
Could you please give me your advice about threshold voltage level with temp dependency? Datasheet explains it is 66.7% of supply voltage. But the 66.7% is typical value. If user should consider it with temperature dependency, should he refer below? Or can user think the 66.7% can apply for all temperature range?

AM6548: programming FlashWriter on AM65xx Platform via TI's uniflash tool.
Part Number:AM6548
Hi,
I am having a try about programming FlashWriter on AM65xx Platform via TI's uniflash tool.
I was following http://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_board.html#programming-flashwriter-on-am65xx-platform steps by steps.
It was all OK until I execute C:\ti\uniflash_4.5.0>dslite.bat --mode processors -c COM6 -f C:\ti\uniflash0\processors\uart_am65xx_evm_flash_programmer.out -d 3 -o 0
The com
mand line outputs "Transferring Header information.." ,
but it remains this status after I wait for 30 minute.
I also tried Erasing Flash Device according to http://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_board.html#erasing-flash-device-on-the-target-platform
I execute the command C:\ti\uniflash_4.5.0>dslite.bat --mode processors -c COM6 -e 10000 -d 3 -o 0
The command line also outputs "Transferring Header information.." and remained this status didn't outputs "Flash Programming Success!"
I wonder why it is always "Transferring Header information.. ",what problem I met?
I really appreciate your help, thanks in advance.

Linux: Boot on SD card when plug out eMMC from Board am572x evm
Tool/software: Linux
Hi TI,
I have a problem with am572x evm board, with BSP's version ti-processor-sdk-linux-am57xx-evm-02.00.01.07-es2.0-Linux-x86-Install. Kerrnel 4.1.13 and uboot 's version is 2015.07.
I want to boot board from eMMC or SD card, I had changed 2 file in uboot source code:
am57xx_evm.h:
#define FAT_ENV_DEVICE_AND_PART "0:1" ==> #define FAT_ENV_DEVICE_AND_PART "1:1"
ti_armv7_common.h:
"finduuid=part uuid mmc 0:2 uuid\0" \ ==> "finduuid=part uuid mmc 2:2 uuid\0" \
and i can boot on eMMC. But when I plug out eMMC (MMC1) from board and only use SD (MMC0), I try to saveenv on uboot command but error:
Card did not respond to voltage select!
** Bad device mmc 1 **
Using default environment
I think this case
(1) uboot only save on MMC1 because define FAT_ENV_DEVICE_AND_PART "1:1"
(2) if i want to save on MMC0, i must change FAT_ENV_DEVICE_AND_PART "0:1"
==> Is this right?
and do you have any advice to change device mmc to saveenv to MMC0
Thanks so much!

Linux/TLV320AIC3104: TLV320AIC3104 mic input config failed
Part Number:TLV320AIC3104
Tool/software: Linux
【Chip model】:
TLV320AIC3104
【Platform】:
Qualcomm MDM9607
【Problem Description】:
Initial plan:
Mic1 left channel input, Right_LOP/M output
There is no problem with this solution.
Current modified plan:
Two channels are used, which are the left mic1 input to the Right_LOP/M output, and the other is the mic1 right input to the LEFT_LOP/M output.
Two channels need to switch between two channels according to demand.
The following four lines, in theory, can control the direction of a single input, but the configuration will not fully take effect afterwards.
Input1 has two input directions, line 1 is connected to Left-ADC and line 4 is connected to Right-ADC.
Input2 has two input directions, line 2 is connected to Right-ADC and line 3 is connected to Left-ADC.
According to our needs, one path is input1 line 4 is connected to the Right-ADC, and the input2 input path is completely disconnected.
The other path is input2 line 3 is connected to the Left-ADC, and the input1 input path is completely disconnected.
The problem arises here. When the input1 line 4 is connected to the Right-ADC and all the input2 input channels are disconnected, the input2 operation register configuration is not valid, and the sounds input by input1 and input2 are simultaneously broadcasted from the output channel; When using input2 line 3 to receive Left-ADC, all disconnect input2 input path, disconnect input2 operation register configuration does not take effect, input1 and input2 input sounds are simultaneously broadcast from the output channel;
The following is our register configuration:
Init configuration:
Input1 channel selection configuration:(Please visit the site to view this file)
Input2 channel selection configuration
Please help to check if there is a problem with the configuration of the villager. Why does it fail to close lnput?

Linux/AM6548: Unable to enable pull-up/down resistor for the GPIO
Part Number:AM6548
Tool/software: Linux
Hello,
I have encountered some problems when I enable pull-up/down resistor for the GPIO. The followings are my steps to reproduce the problem.
For example, I need to enable pull-up for the PIN P4 (WKUP_GPIO0_29)
1. Configure device tree or write 0x00060007 WKUP_PADCONFIG17 (input enable, output enable, pull-up selected, pull enabled)
2. Configure GPIO device as input using the following command
echo 215 > /sys/class/gpio/export
echo in> /sys/class/gpio/gpio215/direction
3. Read input value
cat /sys/class/gpio/gpio215/value
4. Result
the value read from GPIO is 0 when the input pin is floating
What I'm expecting is 1 because of the internal pull-up resistor.
Am I missing anything? Thank you.

TPS659037: I2C interface connection for DVS
Part Number:TPS659037
Hi, In AM572x GP EVM design, the TPS6590376 I2C2 interface is pulled up with 2.2K resistor, but not connected to I2C1 bus, does this mean the processor cannot access the DVS dedicated register, so the DVS is not realized in this design? If this is true, then to realize the DVS, should I unsolder R18, R19, then connect the PMIC_SDO, PMIC_SCE to I2C1_SDA and I2C1_SCL?

BQ24725A: what's the condition for POR?
Part Number:BQ24725A
Hi,
1. what will trigger POR? ACDET rising to 2.4V? So POR is not related to VCC, it's only related to input adaptor, right?
2. When adaptor is unplugged, the device will enter sleep mode, right? My customer tested on our EVM. When they unplug the adaptor but battery exists and connected to VCC, the registers will return to the default value after a while, and then SMBUS stopped working, is this what supposed to be observed?
3. This device cannot set the recharge threshold, right? So when the charge cycle finished at VBAT=8.2V for 2cell battery, how can they achieve only recharge when VBAT<=8.0V?

The battery voltage always form 9-16v in automotive field. some even worse to under 6v. Does it means it’s not suitable for auto?
may i know the reason or the trouble when the input voltage under 11V ?
thanks a lot.
