I've recently downloaded and installed the latest PROCESSOR-SDK-RTOS-K2G on both a windows and a Linux host system with CCS v8. After installation, both installer packages have created directories for mathlib_C66x_3_1_2_2 and dsplib_C66x_3_4_0_1 with nothing in them. I believe some of the examples need these libraries to build.

CCS: CCS v8 installation fails -- Java
Tool/software: Code Composer Studio
Hello,
I have downloaded both the CCS8.1.0.00011 and CCS8.2.0.00007 installers -- the web version AND the offline ones. I am running Ubuntu 16.04:
aero@drone3:~$ cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=16.04 DISTRIB_CODENAME=xenial DISTRIB_DESCRIPTION="Ubuntu 16.04.5 LTS" aero@drone3:~$ uname -a Linux drone3 4.4.76-aero-1.2 #1 SMP PREEMPT Thu Dec 21 09:55:38 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
It looks like both CCS packages for installation come with or download the following file: jre-8u112-linux-x64.zip
The problem is that when the installer attempts to extract this file using p7zip, (7za) there is an error at the end, which apparently the installer checks for and decides to abort (v8.2) with an error mentioning something about "logger:loglist" or keeps re-trying again and again (v8.1). I even tried to use a later version of 7za downloaded from the official website to see if the problem was the outdated extractor (circa 2010), but the same error occurred, which leads me to the conclusion that the archive is corrupt, perhaps.
So, with this issue, I'm at a loss as to how to install CCS v8 successfully currently and do not have a workaround available to install it on the affected system. I have attached a copy of the log of how the 8.1 installer shows the error message after extraction.
Please provide a workaround or solution :)

SN65CML100: SN65CML100 receive sensitivity
Part Number:SN65CML100
Hi there,
We are looking to use SN65CML100 to recover our ac coupled, high speed CML logic (960Mbps) from long cable loss (3m). The eye diagram of the input looks like below, and it is almost closed.
For SN65CML100, we are not sure how low input swing (Vp-p) it could accept, or its sensitivity, given our little eye opening. The datasheet mentioned max positive-going differential input voltage threshold of 100mV. But it is not clear to us what would be the case if the input differential swing is below 100mV, as the datasheet is pretty short in length, compared to SN65LVDS100. I understand there is 25mV hysteresis, but I am not sure how much it is going to help.
In 10.3.1.2 of SN65LVDS100 datasheet, it has the words “When the input signal falls in this –100 mV < VID < 100 mV range, the receiver output state cannot be determined unambiguously. ”. Is that also true for SN65CML100?
Thanks,
Dawei

CC3200: Error "Reading ACK signal failed" with uniflash
Part Number:CC3200
Hello,
I am programming a custom designed CC3200 board using the CC3200 launch pad.
I've connected jumper J6 (Rx) and jumper J7 (Tx) on the CC3200 Launchpad to pin 57 and pin 55 respectively of CC3200 chip on the custom board. The SOP is set to 100.
However, I get the following error in Uniflash"Reading ACK signal failed". The reset pin is pulled low whenever required by uniflash.
I've done this before and it worked fine. I've soldered a new board now and I get the above mentioned error. I do not see any issue with the soldering or connections.
Can you please suggest me possible solutions to debug and eliminate this error.
I've attached my design schematic for reference.

}
}I run the code step by step using F6 and get to the MPU6050Init function.
When this function is called I see (using an oscilloscope) the SDA and SCL I2C lines toggle correctly and the MPU6050 acknowledge to address 0x68.
However, when the transaction is finished the MPU6050 holds the SCL line low and doesn't release it.
According to the I2C specifications - this signifies that the device is serving an interrupt. Only in my case it continues forever.
When I proceed with F6 to the MPU6050ReadModifyWrite function is called and completed - but then when I press F6 again the code gets stuck in the while(!g_bMPU6050Done) { } condition.
Is it possible that MPU6050Init doesn't release the device from reset ?
Similarly to what mentioned in this post:

ADS1282: ADS1282
Part Number:ADS1282
I am using the ADS1282EVM_PDK to evaluate my ADS1282 design. I am in the process of moving all the circuitry from the ADS1282EVM to my board and plan to continue to use the ADCPro platform to test the new configuration. Looking at the ADS1281/82EVM schematic Dated 21/Aug/2008 I have a question on U7 and U14. Is it possible to eliminate these components? Will the code fail to run? I can place a reset switch on my board. Is there a way signal to the code that a ADS1282 is the DUT?

DRV8837: Control of a solenoid using DRV8837, DRV8838...

OK, here goes - testing the friendliness of the Motor Driver region of E2E... (ha!) New to Power Management and Motor Drives, so may ask some noob questions - bear with me. Am beginning my studies.
The Need: I'd like to incorporate control of a solenoid into a design which will likely be based on the MSP432E family. Plan is to drive design power over PoE, so will have 48V available at the start.
Part of the design will drive a solenoid - requirements are ~12v @ < 1 amp for 2-3 seconds.
Will one of these parts - DRV8837, DRV8838 - get me there? Other componentry in the mix? Overview design advice will be appreciated.

TDA2PXEVM: Unable to format SD card for boot
Part Number:TDA2PXEVM
Hi,
I'm trying to format the included SD card for the TDA2P board in order to boot from it.
When I try to format from the command line, I get a "The specified cluster size is too small for FAT32" error. When I try to format using diskpart, I get "The cluster size is too small" error.
When I load the generated Appimage and MLO onto the unformatted SD card, the TDA2P is unable to boot from it.
I have also tried to format a store-bought SD card, but get the same cluster size errors.
How can I correctly format the SD card to boot from it?

RTOS/CC2640R2F: Simple_Central.c BLE Functions
Part Number:CC2640R2F
Tool/software: TI-RTOS
Hello,
I am currently developing a custom application around the simple_central example. I have a custom PCB with the SABLE-X-R2 module on it with several buttons, sensors, and a display. I am trying to get the simple central application merged with another application that I have for reading sensors, talking over SPI with the display, and other things.
I am having trouble making sense of the flow of the functions in the simple_central.c file. I have two buttons on my board that I would like to use to navigate the menu for the example, but I don't want to have them as interrupts like defined in the board_key.c file. I tried calling just the SimpleCentral_startGapDiscovery(); and then the SimpleCentral_connectToFirstDevice(); in my own application thread, but it goes into an aport spin loop.
What is the proper way to go about merging the functionality from the simple_central example into a custom application? I have been unable to find documentation that goes over the specifics of the simple central example and the structure of the program.
Thanks,
Josh

TMS570LC4357: L2FMC#5 with the flash prefetch disabled part of the time
Part Number:TMS570LC4357
I have a requirement to read some configuration information out of the EEPROM FLASH area at startup time. I would also like to keep the flash prefetch unit enabled, and all of the data FLASH address space mapped as normal memory after startup. Can you confirm whether this sequence of operations is subject to errata L2FMC#5?
- Device starts up (with flash prefetch enabled per default), running code out of data FLASH
- Disable flash prefetch
- Continue executing code out of data FLASH throughout
- Read some data from the EEPROM FLASH
- Re-enable flash prefetch
- Go on to enable the MPU with the data FLASH mapped as normal memory

TPS24751: XOR two devices
Part Number:TPS24751
I'm trying to 'or' two TPS24751 where if first one has a valid source voltage applied, the second one is shut down. I have the first one's PG# connected to EN pin of second device. After I applied a valid source voltage to first device and an open source on second device, the second device slowly burned itself up, literally with a blackened board around its VCC pin. What is the correct way to 'OR' these two? [ FYI when the TPS65990 is no longer preliminary I intend to replace just the second device. My intent is to have one USB C source and one optional wall/car adapter to run/charge my device. The output to the right feeds 50uF of ceramic caps and a BQ257503 ]

BQ27GDK000EVM: GDK general questions
Part Number:BQ27GDK000EVM
Hello,
I am looking into the GDK as a solution for the calculation of the CHEMId for my Lithium Ion Battery (Charging Voltage = 4.2 V). This tool is great because compared to using a EV2400 we can control the charger and load using a script from bqStudio. This means, after everything is setup, we can leave the characterization running.
After looking at the documentation, I have the following questions:
1- In my device, I am planning to use a BQ24232 (linear charger) and this GDK has a switched mode charger. Would using the charger provided by GDK make a difference in the estimation of CHEMID? I mean, differences regarding accuracy compared to when the battery is in our device. I would say this can be solved with a learning cycle in the device but I am not sure.
2- How is it normally used to measure the temperature of the battery for the CHEMID? Does the battery need to be placed in a specific position in order to use the internal sensor of the on board gauge? I think I would be ok with using the internal gauge but I would like the temperature reading to be accurate enough for GPCCHEM.
3- The battery has an NTC so I thought I could also use the bq27520evm (has an NTC pin) and connect it to the GDK. By the way, if I can not use a ROM based gauge, I would use this gauge. One thing I did not understand for this gauge is figure 6 of SLUU426B. Do I need a 3.6V power supply or is the figure wrong?
4- Should I calibrate the gauge before doing the characterization of the battery?
Thanks for your help!
