HI everybody ,
my goal is to use BSL and avoid somebody to erase the device and put their code on my board ( using my logo etc ) .
If I well understood when using BSL with a password , a bad password force a mass-erase , am I right ?
using Signature I can avoid this since only a proper signature allow me to enter BSL : am I right ?
thank you
regards
Carlo
PS Jtag is disbaled by me to avoid attack from there .

Hi,
I would like to disable all the resize/crop/algorithm made on the input image of the lightcrafter.
My input image is in RGB 24 bits, format 1280x720 sent at 60 FPS. I would like to display them exactly wihout any modification from the lightcrafter. Image crop is set as following:
Start Pixel: 0
Start Line: 0
Pixels per line: 1280
Lines per frame: 720
However, I see black borders around my output display, which makes me think that my input image has actually been a little bit cropped to add these borders... Am I right ? Is there a way to get rid off these borders ? Is there any thing else I should disable/enable ?
Kind regards,
Julie
I need to use a linear regulator to get an output with low noise <1mV, but the output needs to vary between 0-5V@2A So I was thinking that I could use a dcdc on the input of the linear to reduce power by only having the minimum amount of head room. Are there any parts or circuits that would allow me to do this. Vary the linear from 0-5V and then vary the dcdc to maintain the mimimum head room of the linear.
Thanks

Part Number:TCA9555
Hi,
i have configured TCA9555 port 0 as input and port 1 the first 4 pins configured as input and rest of the pins configured as output. TCA9555 is used along with TM4C292NCPDT for input operation. The device is generating the interrupt continuously as long as if we give input in either one of the port making all pins HIGH or LOW. but if we give inputs with combination of two ports over the minute period, its failing to generate the interrupt after either Master reads ports status or port input status changes. the interrupt pin is always de-asserted.
Can anyone suggest what could be the reason for this behavior?

Part Number:AM3352
Hi,
We are developing a board with the AM3352 CPU. For programming we are hoping to use the USB0 boot-mode and then UniFlash to program over "Ethernet over USB"/RNDIS. To test this out before sending the final PCBA for production we are using a Beaglebone Black.
Our production programming and test environment use Windows 10 as OS.
When we connect the BBB over USB to our computer (pressing button S2 on the BBB board and have no SD-card attached) W10 enumerates the CPU as a serial device and we get a COM-port. I have seen others with this issue while searching the Internet (but no solution). On an old Windows 7 somputer I found stored away it works. W7 enumerates the CPU as "other device" and I can install the correct driver. And later on UniFlash will recognize the CPU and we are able to program it.
Is it possible to get this working on Windows 10? Have anyone made it work? Should we rethink our programming strategy and program the eMMC onboard some other way? In worst case we could use UART0, but that would take for ever to program the board.
Thanks in advance!
Regards,
Jonas

Part Number:SN74LVTH16245A
Hi,
I'm looking for a transceiver with the same form factor as the SN74LVTH16245ADGG, but with a slower propagation delay (> 1.5ns Min.). I saw the 74LVCR16245A, which has the same Min t_pd, but a slower Max. Does anyone know of another with a slower Min t_pd?
Thanks in advance.

Hi,
I am searching an current amplifier which is able to amplify micro amp range to miliamp range current and expect to have faster response time, can you introduce me an amplifier?
Thanks. :-)
Part Number:AM5728
Hi
Is it possible to swap the two USB3.0 (super speed) signals within the transmit differential pair with each other?
USB Type-C connector pins A2/B2 (TX1+) => usb_txp0 is routed to AC11 of the AM5748
USB Type-C connector pins A3/B3 (TX1-) => usb_txn0 is routed to AD11 of the AM5748
The receiver differential pair is left untouched. Does anything need to be re-configured in boot loader? This makes routing of the high speed signals much more easier.
Thanks and best regards,
R
Part Number:TMS320F28234
Hello,
This is related to the thread "eQEP - Position Counter Reset on the First Index Event not available after SW reset". I find that the "Position Counter Reset on the first Index Event" mode of the PCCU in the eQEP module works as described, but only after a device reset. If, after the First Index Event has be acquired and the FIMF has been set, the eQEP peripheral is reset (QEPCTL.QPEN = 0) and/or the First Index Marker Flag has been cleared (EQep1Regs.QEPSTS.bit.FIMF = 1), the device will not reacquire the First Index Event.
Has this issue been confirmed as a bug and is there a workaround other than resetting the device?
Thanks in advance.

Part Number:TMS320F28377D
Hello
I'm working on a BLDC motor control.
My board is very similar to the demo board with the ControlCard F28377
The software base from the exemple IDDK v2.0.
My feedback is the Qep + Hall.
In a Calibration step, I get the number of Qep increment between the Electrical zero and the TopZ Event.
Then After that, the Qep is configured to Reset on TopZ event. compute the Electrical angle by retreive this angle to obtain RawValue = 0 on the true electrical angle.
In a normal life, I get the Hall captor and apply to the Qep Counter the position according the captor (+Angle Shift given by calibration step)
On the First Hall sensor change value, I make the same because now, we sure we are exactly on the transition of two hall combination.
Then on the TopZ event, the Qep counter is set to 0 and then now, I'm exactly on the good position.
This work correctly, BUT sometime, between the Hal Captor rising edge and the TopZ, I see the QepCnt reset to 0 without any reason! (No Top Z FLG.IEL = 0)
I'm using the QEP computation given on the IDDK exemple, the flag IndexSyncFlag is not set.
What could be Reset the QEP counter excepted the TopZ in my case???
The Qep Config is following:
/*-----------------------------------------------------------------------------
Initialization states for EQEP Decode Control Register
------------------------------------------------------------------------------*/
#define DV_QEP_QDECCTL_INIT_STATE ( XCR_X2 + QSRC_QUAD_MODE )
/*-----------------------------------------------------------------------------
Initialization states for EQEP Control Register
------------------------------------------------------------------------------*/
#define DV_QEP_QEPCTL_INIT_STATE ( QEP_EMULATION_FREE + \
PCRM_INDEX + \
0 + \
IEL_RISING + \
QPEN_ENABLE + \
QCLM_TIME_OUT + \
/*UTE_ENABLE*/0 )
/*-----------------------------------------------------------------------------

------------------------------------------------------------------------------*/
#define DV_QEP_QPOSCTL_INIT_STATE PCE_DISABLE

Initialization states for EQEP Capture Control Register
------------------------------------------------------------------------------*/
#define DV_QEP_QCAPCTL_INIT_STATE ( UPPS_X32 + \
CCPS_X128 + \
CEN_ENABLE )
The computation of the Electrical angle is following:
{ \
float32 ElecThetaTemp; \
/* Check the rotational direction */ \
IF_MotorPosition_iQep.DirectionQep = (*DV_Qep_Regs[2]).QEPSTS.bit.QDF; \
\
/* Check the position counter for EQEP1 */ \
IF_MotorPosition_iQep.RawTheta = (*DV_Qep_Regs[2]).QPOSCNT - IF_MotorPosition_iQep.InitTheta; \
\
if (IF_MotorPosition_iQep.RawTheta < 0) \
IF_MotorPosition_iQep.RawTheta = IF_MotorPosition_iQep.RawTheta + (*DV_Qep_Regs[2]).QPOSMAX + 1; \
else if (IF_MotorPosition_iQep.RawTheta > (*DV_Qep_Regs[2]).QPOSMAX) \
IF_MotorPosition_iQep.RawTheta = IF_MotorPosition_iQep.RawTheta - (*DV_Qep_Regs[2]).QPOSMAX - 1; \
\
/* Compute the mechanical angle */ \
IF_MotorPosition_iQep.MechTheta= IF_MotorPosition_iQep.MechScaler*IF_MotorPosition_iQep.RawTheta; \
/* Compute the electrical angle */ \
ElecThetaTemp = IF_MotorPosition_iQep.PolePairs*IF_MotorPosition_iQep.MechTheta; \
IF_MotorPosition_iQep.ElecTheta = (ElecThetaTemp) -floor(ElecThetaTemp); \
\
/* Check an index occurrence*/ \
if (((*DV_Qep_Regs[2]).QFLG.bit.IEL == 1)) \
{ \
IF_MotorPosition_iQep.IndexSyncFlag = 0x00F0; \
IF_MotorPosition_iQep.QepCountIndex = (*DV_Qep_Regs[2]).QPOSILAT; \
((*DV_Qep_Regs[2]).QCLR.bit.IEL = 1); /* Clear interrupt flag */ \
} \
\
/* Check unit Time out-event for speed calculation: */ \
/* Unit Timer is configured for 100Hz in INIT function*/ \
if((*DV_Qep_Regs[2]).QFLG.bit.UTO == 1) \
{ \
/***** Low Speed Calculation ****/ \
if(((*DV_Qep_Regs[2]).QEPSTS.bit.COEF || (*DV_Qep_Regs[2]).QEPSTS.bit.CDEF)) \
{ /* Capture Counter overflowed, hence do no compute speed*/ \
(*DV_Qep_Regs[2]).QEPSTS.all = 0x000C; \
} \
else if((*DV_Qep_Regs[2]).QCPRDLAT!=0xffff) \
/* Compute lowspeed using capture counter value*/ \
IF_MotorPosition_iQep.QepPeriod = (*DV_Qep_Regs[2]).QCPRDLAT; \
} \
}This comes only before the TRUE real TopZ signal. Never after.
Thank for your help.

I'd like to have the option of only using a single channel output and input. What should I do with the inputs and outputs of the unused channel? I did not see any comments on this in the datasheet.
Thank you
