Hello, Below , you find the answer to your question : * Is the address supposed to point to the base PL310 address? Yes , you have to provide the physical address of PL310. * Why do you call this operation if the target status is unknown?
ð After target creation and smp initialization, this operation need to be done only once. ð By doing it with target in unknow state, It is not performed several time, if operation is done several time, only 1st call is taken into account. * What does this operation do when called? ð This operation is initializing the l2 cache handler with external cache PL310. (without this initialization cache l2 is not supported) ð The number of way is provided as parameter, auto detection is not implemented yet. ð The effect of this call is seen later on : -1- while reading phys memory through dap apsel 1: a flush of the cache L1 from the cortex A9s and then a flush of unified cache L2 will be done. This will allow to read a consistent physical memory. -2- cortex_a8 cache_info : shows the cache L1 and L2 info Best Regards Michel JAOUEN
