TDA4AL-Q1: usage of OCRAM

Part Number: TDA4AL-Q1

Tool/software:

Hi expert,

Our customer plans to use OCRAM at address 0x60080000 in the MCU21 of TDA4AL. However, they found that when they put the data segment into OCRAM, the MCU21 stops running. When we accessed it through Lauterbach, we saw that all the data in OCRAM was zero. Directly writing data through Lauterbach resulted in a bus error, as shown in the figure below. They would like to know if there is any pre-configuration required for using OCRAM? Thanks

Best Regards,

Xingyu Zhu
