currently im using imx8 processor. im runnning autosar on m core and qnx on A core. initially we run both a and m core from DDR and it was working fine.
But wen i started loading big applications on A core. Performance of m core impacted badly. pit timer isr get affected by huge margin.
as a alternative solution we move code of the m core from ddr to tcm. after doing that, things appeared normal even after heavier loading at the a core.
bt sadly, for a fully developed m core will have slight bigger memory to make it difficult to fit in tcm memory [ 256 kb ].
for example, lets take my m-core memory will be of 900kb.
wats ur expert advice. how should i handle this scenario ????d
