Hello,

Yes after reinstalling it is working fine.

Thank you.

Hello,

This could be caused by a faulty connection, or a bad Segger install.
Could you ensure that the connection between the nRF52833 SoC and the J-Link is in good condition?
Please see this ticket for details around resolving a bad Segger install - in essence it seems that you will need to reinstall Segger and the related JLink drivers to resolve this issue.

Could you reinstall SES and J-Link driver, and let me know if this resolves your issue?

Best regards,
Karl

Target->Download File->Download

It says Generic Error

Is there any particular SES version for this nRF52833 SoC? We use version 4.22.

[quote user="Jonnavittula sridhar"]Yes, our custom board has JLink pins out and connected via debugger.[/quote]

Alright, this is good to know, that changes things.

[quote user="Jonnavittula sridhar"]So when debugger USB interface is connected to Windows PC which runs SES cant able to download prebuilt hex file ble_app_uart_pca10100_s140.hex using Download Intel Hex file option but nRF Connect for desktop Programmer application and nrfjprog can download in the same Windows PC.[/quote]

Are you able to connect to the JLink from SES? Is there an error prompt when you try to use the "Target->Download" button? If so, which one?

[quote user="Jonnavittula sridhar"]Furthermore, be advised that the ble_app_uart PCA10100 project is made for the nRF52833 DK specifically, and it is not guaranteed to work right off the bat on a custom board - due to possible differences in the PCB's.[/quote]

I do not understand what you mean by this including this quotation from my previous reply, please elaborate.

[quote user="Jonnavittula sridhar"]Why SES cant even program?[/quote]

SES should be able to program your device just fine as long as it is connected to the JLink, which in turn is connected to your nRF52833 SoC.
Please specify what behavior you are seeing when you attempt to use SES to program your device.

Best regards,
Karl

Yes, our custom board has JLink pins out and connected via debugger.

So when debugger USB interface is connected to Windows PC which runs SES cant able to download prebuilt hex file ble_app_uart_pca10100_s140.hex using Download Intel Hex file option but nRF Connect for desktop Programmer application and nrfjprog can download in the same Windows PC.

Hello,

How is the nRF52833 SoC connected to your computer - do you have it connected to a debugger?
SES will need a J-Link interface to program and debug your SoC.
The nRF Connect programmer can write a prebuilt .hex directly to your MCUbootloader.

Furthermore, be advised that the ble_app_uart PCA10100 project is made for the nRF52833 DK specifically, and it is not guaranteed to work right off the bat on a custom board - due to possible differences in the PCB's.
