Build failed with SDK v12.3.0 in SES

[joycel]

Hello,

I am using MacBook and would like to import Keil Projects into Segger Embedded Studio by following this guide, but finally I got an error is that

I have found other related solutions like this link and this link, but it couldn't help.

Thanks in advance.

Keil uses ARM's own toolchain - including assembler.

Segger use the GCC toolchain - the GCC assembler is not the same as the ARM assembler.

I am already choosing internal toolchain by following the guide mentioned above.

Now I found that use .syntax unified than it works now, thanks!

However, I found that nRF51822 evaluation board is PCA10001. Can I edit some configs like this so that SDK 12.3.0 can runs on that board?

Note that nRF51 are not (and have not been for several years) recommended for new BLE designs:
