Stu,

You may have better luck searching with google using the option "site:community.silabs.com" with the keywords you are searching for.

Which device is on the ESP32 board?  CP2102, CP2102N, or a different bridge part?  Does this only happen with the ESP32 board, or with a Silicon Labs EK?

Hi Rob,

try using quotes around the filename in the include statement instead of the angle brackets <>.  The angle brackets should work for any path in the Includes, since the INCDIR directive is used for them, but the compiler searches more places for user include files.  From the Keil C51 reference manual:

System header files are included as follows:

#include <filename>

These include files are installed in the \INC\ folder. They are a part of the Keil development tools release and should not be modified. When a system header file is specified, the compiler searches for the file in the following folders in order:

• Paths specified by the INCDIR directive.
• Paths specified by the C51INC environment variable.

User header files are included as follows:

#include "filename"

These include files are user-created and may reside anywhere on your computer. When a user header file is specified, the compiler searches for the file in the following folders in order:

• The current folder.
• The source file folder.
• Paths specified by the INCDIR directive.
• Paths specified by the C51INC environment variable.

If that does not work, then it would be helpful to get a project export that demonstrates the issue.

Thank you,

I don't think we have any specific information about this.  You can minimize the transition time by putting the pin into push pull mode and setting the drive strength to high.  See section 28.5.1 of the reference manual: https://www.silabs.com/documents/public/reference-manuals/EFM32G-RM.pdf

Hi Arun,

There is an example application for HID to UART in our direct access driver package: https://www.silabs.com/products/development-tools/software/direct-access-drivers, usually this will be installed to C:\SiliconLabs\USBXpressHostSDK\CP2110_4\Examples\HidUartExample  

I don't what hardware you are using.  Is this a board with a CP2110?  How is it connected to a hard drive, which pins do you need to change to reset the hard drive?  

Regards,

Joe

Uros,

I have created a new configurator project for the UB1, and added USB.  I am not able to reproduce the error you are seeing.  What version of the SDK are you using?  Can you attach your project file to this thread?

Joe

Harshal,

Our VCP drivers are available here: https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers

The .dmg file contains a "Troubleshooting" folder with a .pkg file that you can use.  These files are notarized and stapled.

If you are incorporating this .pkg into another pkg, you may have to sign the whole package.  I'm not aware of the details of this, contact Apple support if you have any questions about it.

Joe

What revision of the GG11 are you using?  This sounds like errata RMU_E203, which affects revision A but is fixed in revision B.

See the errata (https://www.silabs.com/documents/public/errata/efm32gg11-errata.pdf) and this KB article (https://www.silabs.com/community/mcu/32-bit/knowledge-base.entry.html/2017/06/14/rmu_e203_avdd_ramp-j176) for more information.

Hi Anthony,

What voltage does the supply drop to when this happens?  How low does the supply have to go before it recovers?

Since this is a custom board, can you share the schematics?

Regards,

Joe

Hi,

The mainboard schematic is available here: https://www.silabs.com/documents/public/schematic-files/WSTK-Main-BRD4001A-A01-schematic.pdf

The daughterboard schematic is available in the documentation section of Simplicity Studio, and is attached to this post.

Please let me know if you have any questions.

Regards,

Joe
