Hi Shuyang Guan,
when programming with Cortex-M4 in i.MX8x, we found that the total size of TCM is 256k,
this size is too small to meet our some product application requirements.
so we plan to enable ocram for Cortex-M4, take i.MX8x DualX for example,
we can use TCM as code section and use ocram as data section, please help us to check whether it is available or not .
