[microblaze-uclinux] Crash with cache

[arnaud.lagger@xxxxxxx]

Hello everybody.

I cannot run uClinux with Cache enabled.

The problem is that I use 6 MB (I cannot afford to run on 4 MB) and everytime I
boot on uClinux, it hangs or it restarts.

Some tests with the XIL kernel showed that the cache was properly working.

The parameters in my .mhs for the cache are:

****

 PARAMETER C_USE_ICACHE = 1
 PARAMETER C_ICACHE_BASEADDR = 0x80000000
 PARAMETER C_ICACHE_HIGHADDR = 0x805FFFFF
 PARAMETER C_CACHE_BYTE_SIZE = 16384
 PARAMETER C_ADDR_TAG_BITS = 8
 PARAMETER C_USE_DCACHE = 1
 PARAMETER C_DCACHE_BASEADDR = 0x80000000
 PARAMETER C_DCACHE_HIGHADDR = 0x805FFFFF
 PARAMETER C_DCACHE_BYTE_SIZE = 16384
 PARAMETER C_DCACHE_ADDR_TAG = 8

****

I also tried:

****
 PARAMETER C_USE_ICACHE = 1
 PARAMETER C_ICACHE_BASEADDR = 0x80000000
 PARAMETER C_ICACHE_HIGHADDR = 0x805FFFFF
 PARAMETER C_CACHE_BYTE_SIZE = 8192
 PARAMETER C_ADDR_TAG_BITS = 9
 PARAMETER C_USE_DCACHE = 1
 PARAMETER C_DCACHE_BASEADDR = 0x80000000
 PARAMETER C_DCACHE_HIGHADDR = 0x805FFFFF
 PARAMETER C_DCACHE_BYTE_SIZE = 8192
 PARAMETER C_DCACHE_ADDR_TAG = 9
****

But it failed also.

Any idea?
