AM2634: sbl_qspi example not build

Hello,

MCU : am2634

Sysconfig : 1.19.0

SDK : 9.1.0.41

Compiler : Ti_Clang v3.2.1.LTS

I am using it as above, but it is not built to build an example of SBL_QSPI.

When I searched forum, it seems that this happened in version 9.0.0.30

How can I solve it?

Thank you
