hello,
i am working with s32k324, decoupled mode(core0 and core1 run independently).
s32k324 has 128kb dtcm and 64kb itcm in total. each core has 64kb dtcm and 32kb itcm as dedicated memory. we can say that they act as core local memory and we can access the other cores memory via dtcm/itcm backdoor addresses. however, i want to configure it in a way that both core can access whole capacity of memory directly(not via backdoor addresses)
currently, each core can access address range below
dtcm -:0x20000000 - 0x20010000 - 64kb
itcm - 0x00000000 - 0x00008000 - 32kb
i want to have address range as below and access the same data from both core. that, means tcm memory will not be core specific but global between all cores.
dtcm -:0x20000000 - 0x20020000 - 128kb
itcm - 0x00000000 - 0x00010000 - 64kb
i tried to configure it as below however, it didnt work
Hello Mahmut,
I'm afraid this is not possible.
The CM7_1 TCM is added to the primary core in the lockstep mode only,
