is it possible to disable the i-cache on the e200z4 usign VLE?
Yes, it is possible. It does not matter whether BookE or VLE mode is being used. Cache memory can be disabled/enabled in both cases.
Thank you, but the following inline code
asm("mtspr L1CSR1, %r31");
produce the following error:
Error: unsupported relocation against L1CSR1
and at this point I don't understand why
Is L1CSR1 defined? (i.e. ".equ") Otherwise, it will be considered as a symbol name and will produce the relocation error you mentioned. So, if L1CSR1 is not natively supported in your compiler, then add the following:
.equ L1CSR1 1011
to declare the SPR number matching L1CSR1.
