tcb_object.size_bits is a

Any advice about the issue?

another question that why set
the sp in monitor mode to sp in SVC mode.
asm volatile ("mov r8, sp\n\t"
"cps %0\n\t"
"isb\n"
"mov sp, r8\n\t"
::"I"(MONITOR_MODE));
Thank you,

0, 1"::"r"(MON_VECTOR_START));
I enter into SVC mode by software interrupt and call the function smc():
asm (".arch_extension sec\n");
asm volatile ("stmfdsp!, {r3-r11, lr}\n\t"
"dsb\n"
"smc #0\n"
