" Output/Debug/Obj/uart_pca10056/thumb_crt0.o: in function `_start':" when trying to build uart example

[bido1234]

Hi,

im using sdk 17.1 with segger embedded studio v6.2a and nrf52840. I am trying to use the uart example and it gives an error no name type found "__printf_tag_ptr". I searched for this problem here. A couple of answers suggested that i try a previous segger version which was used for testing of the sdk im using. So i tried installing segger v5.42a.It gave me an error " Output/Debug/Obj/uart_pca10056/thumb_crt0.o: in function `_start':" any suggestions how to get it to work ? thank you,

Hi.

From the documentation:

The following toolchains/devices have been used for testing and verification:
 
 - ARM: MDK-ARM version 5.25   
 - GCC: GCC ARM Embedded 9.2020-q2.major
 - IAR: IAR Workbench 7.80.4
 - SES: SES 5.42a

Does this happen to the stock example from the SDK? You haven't made any changes to the example?

Can you explain what you did with the thumbcrt0.o file exactly.

I'm using segger 5.68v. Faced the same issue.
