MSP430FR2632: How can i tell from data registers the number of memory address locations that I tried clocking through to compute the PSA_CRC?

Part Number:MSP430FR2632

I have a SOC that has 2 GPIOs tied to the RST and TST line of the MSP430FR2632 microcontroller. On the SOC, I am running Linux. When I try to compute the PSA, the kernel side driver is responsible for shifting in the instruction IR_DATA_PSA and subsequently clocking through the appropriate number of memory address location. In this setup, there might be instances whereby the clock signal is messed up because the kernel gives run time to other operations. Is there a way to check for the number of memory locations that I tried to clock through post reading out the PSA_CRC after shifting in the instruction IR_SHIFT_OUT_PSA? This will give me a sense of whether I was successful in the clocking the data.

Hi, TI and everyone!

I am using VMware Ubuntu 16.04LTS, ti-processor-sdk-linux-am57xx-evm-04.03.00.05 and AM57xx EVM.

I have created the TF card several times using create-sdcard.sh, then the consumption time is about 2~3 hours.

Is this normalcy?

Thanks.

Part Number:TPS62175

Hi team,

I have some questions about TPS62175.

1. When they don't use Sleep mode, should they connect SLEEP-pin to VOS-pin?

2. What is the recommended min value of the resistive divider? The datasheet mentions that the value is recommended to allow a current of 5uA and lower values are recommended, but no sure the min value.

3. Could you share the min/max values of Internal Voltage Reference(VREF)?

SN74LVC1G66: The input voltage question for SN74LVC1G66

Part Number:SN74LVC1G66

Hi team,

I want to use SN74LVC1G66. VCC is 3.3V.  The datasheet shows the I/O port voltage range is from 0 to VCC.

Q1:I want to confirm if the input voltage exceeds 3.3V, can the input pin be damaged?

Q2: From the datasheet, 6.1 Absolute Maximum Ratings shows the max switch I/O voltage is  (vcc+0.5)V, So, if the input voltage exceeds 3.3V+0.5v=3.8V, then the input voltage can be damaged, correct?

Q3: Can I use 5V input voltage when VCC is 3.3V?

Hello,

I'm attempting to build the tisdk-rootfs-image on Processor SDK Linux 5.00.00.15 using bitbake and I'm running into an error building the tiovx-lib-host.bb recipe.

I'm getting the error below:

| In file included from /usr/include/features.h:367:0,
|                  from /usr/include/stdio.h:27,

|  #if __GNUC_PREREQ (4,8) || __glibc_clang_prereq (3,5)

It looks like the error actually is in a header in the linaro toolchain. I am using the toolchain distributed with the SDK, and I have cleaned and re-downloaded from source the git repository. Any insight as to why I might be seeing this error is appreciated. Other components of the SDK have built fine so I don't think it's an issue with my environment setup.

Munan

WEBENCH® Tools/TPS54360: Hot Plugging Burnout with TPS54360

Part Number:TPS54360

Tool/software: WEBENCH® Design Tools

I'm experiencing repeated catastrophic failure of the TPS54360 when it is plugged into an active power source.

In particular, I have the TPS54360 setup to convert 48V DC to 6.5V DC for power over Ethernet. When the Ethernet cable is connected with the system off, turning on the power supply results in normal operation. However, when the Ethernet cable is connected after power is already supplied to the system, the TPS54360 fails dramatically. This happens with some regularity, though not every time the device is hot plugged. I have been able to reproduce this behavior.

I'm using a recommended WEBENCH configuration for the TPS54360 and a Mean Well supply for the 48V. Any recommendations about the potential problem (and how to solve it) are appreciated.

LAUNCHXL-CC1352P: MT_SysResetInd doesn't work in ZNP project of simplelink_zigbee_sdk_plugin_2_20_00_06

Part Number:LAUNCHXL-CC1352P

MT_SysResetInd doesn't work in ZNP project of simplelink_zigbee_sdk_plugin_2_20_00_06.  After checking source code, I find MT_Init is called before NPITask_inititializeTask and this causes MT_SysResetInd doesn't work. If I move MT_SysResetInd to right after NPITask_inititializeTask is called in NPITask_task. It will work. However, I don't think this is an elegant fix so please TIers have a look on this issues and provide fix.

void NPITask_task(void)
{
    // Initialize application
    NPITask_inititializeTask();

    MT_SysResetInd();
    // No return from TestProfile2 process
    NPITask_process();
}

TLK10031: LS(XAUI) part & HS part(10KR) link

August 12, 2018, 7:49 pm

Part Number:TLK10031

Hello,

We are using the TLK10031 to convert from XAUI to 10GBASE-KR. The below figure shows the data flow path in our design:

SWITCH<------------->TLK10031(LS)<------------>TLK10031(HS)<------------>SFP+

                  XAUI                                                                        10GBaseKR

TLK10031 is configured  following this procedure:

1. Reset device (write a 1 to 0x1E.0000 bit 15 or assert RESET_N pin)
2. Make sure the reference clock selection (156.25 MHz or 312.5 MHz) is correct – this is done through register 0x1E.001D bit 12 (default is 156.25 MHz).
3. Disable auto-negotiation by writing 1’b0 to 0x07.0000 bit 12
4. Disable link training by writing 16’h0000 to 0x01.0096
5. Write 16’h03FF to 0x1E.8020. This allows the link settings that would normally be configured through KR training to be configured manually instead.
6. Depending on the link conditions, you may need to change the default configuration of 0x1E.0003 and 0x1E.0004. For optical connections, we typically recommend changing HS_ENTRACK (0x1E.0004 bit 15) to 1’b1 and HS_EQPRE (0x1E.0004 bits 14:12) to 3’b101. This can be a starting point, but you may need to do some BER testing to optimize the values.
7. Issue a data path reset by writing 1’b1 to 0x1E.000E bit 3.

At this point the device is properly configured.and it's status register is :

Read Verify 30.15 CHANNEL_STATUS_1 – (16’h5C03)
o Read Verify 30.16 HS_ERROR_COUNTER – (16’h0000)
o Read Verify 30.17 LS_LN0_ERROR_COUNTER – (16’h0000)
o Read Verify 30.18 LS_LN1_ERROR_COUNTER – (16’h0000)
o Read Verify 30.19 LS_LN2_ERROR_COUNTER – (16’h0000)
o Read Verify 30.20 LS_LN3_ERROR_COUNTER – (16’h0000)
o Read Verify LS status register for each lane
ƒ Write 2’b00 / 2‘b01 / 2’b10 / 2’b11 to 30.12.13:12 to access LS lane 0 / 1 / 2 / 3
ƒ Read Verify 30.21.10 LS_LOS (1’b0)
ƒ Read Verify 30.21.8 LS_CH_SYNC_STATUS (1’b1)
ƒ Read Verify 30.21.3 LS_INVALID_DECODE (1’b0)
o Read Verify 1.1.7 FAULT (1’b0)
o Read Verify 1.1.2 RX_LINK (1’b1)
o Read Verify 3.1.7 PCS_FAULT (1’b0)
o Read Verify 3.1.2 PCS_RX_LINK (1’b1)

It shows TLK10031 is configured properly，and the link is up both LS side and HS side .

Now the question is :

    When i send data (ping operation ) form SFP+(connected to PC), i should get /D/ code  form the XAUI lane0~lane3, But I just get /A/ /K/ /R/ code, which means the XAUI is in idle state and it do not send data to it's partner.  So how can i known TLK10031(HS) side to TLK10031(LS) side is OK ?
