在编译LPC55S69的SDK出现如下问题，pack都是安装的，不知道是什么问题，有遇到过吗
ArmClang: error: ARM Compiler does not support '-mcpu=cortex-m33'
Hello haifeng jin,
Yes, as sean said, you need Professional license.
Do you still have question about this?
Hello
Starting with Keil MDK 5.31, a MDK Pro license will not be needed for Armv8-M (Cortex-M23, M33, and so on).
Other versions of MDK will work with these TrustZone processors.
Even MDK-Lite (the evaluation version) will work to 32K.
MDK 5.31 is expected to be released early July 2020.
I just updated my LPC55S69 lab: www.keil.com/appnotes/docs/apnt_322.asp
ok，谢谢，确实是licensec问题
LPC55 is ARM V8 cortex m33.
You need professional Keil version to compile it.
