Other Parts Discussed in Thread: SYSBIOS
Hi,
About the contents of related posts.
My question 1:
Are there any way to clean L1 instruction cache (like data cache) from user program?
Frank's answer:
Q1: It seems you would use the Cache_wb() API function with the 'type' argument set to "Cache_Type_L1P'
After checking SYSBIOS (bios_6_76_00_08), Cache_wb () API seems to clean Data Cache.
(Irrespective of the argument)
C:\ti\bios_6_76_00_08\packages\ti\sysbios\family\arm\a15\Cache_asm_gnu.asm
mcr p15, #0, r0, c7, c10, #1 @ write back a cache line
We think Cache_wb API can't clean the instruction cache.
Is there any other way?
