Hi,
I notice slow tftp transfer on mx53qsb and I suspected it could be due
to L2 cache being disabled.
Tried enabling with:
--- a/arch/arm/cpu/armv7/mx5/lowlevel_init.S
+++ b/arch/arm/cpu/armv7/mx5/lowlevel_init.S
@@ -45,6 +45,11 @@
#endif
mcr 15, 1, r0, c9, c0, 2
+
+ /* enable L2 cache */
+ mrc 15, 0, r0, c1, c0, 1
+ orr r0, r0, #(1 << 1) /* enable l2 cache */
+ mcr 15, 0, r0, c1, c0, 1
.endm /* init_l2cc */
/* AIPS setup - Only setup MPROTx registers.
,but still see the same low tftp throughput (720 kB/s - on mx28 I see
the double rate).
Any suggestions as to how properly enable L2 cache on mx53?
Thanks,
Fabio Estevam
