Hi TI
We work on the memory register read /write in the R5F main domain mcu2_1 of the J7200 evm board. We use SD card boot to bring up the device.
Refer to the guide line "Ethernet Firmware Demo",
When we try to use a pointer to read /write the address 0x46020004 of the CPSW register in mcu2_1 ( as below image1) ,there will be no problems.
The memory can be read/written normally.
But when we try to read /write the address 0x2140110 of the SPI register in mcu2_1 (as below image2),
the memory read /write does not work, and we also try to call the function HW_WR_REG32_RAW (addr, value)/HW_RD_REG32_RAW (value) to read /write address 0x2140110,
we also cannot read and write normally. Is this a question about SD card boot code setting about memory-related protection? (tiboot3,tifs ,) How do we solve this problem?
Because we are currently doing software integration, we need to do some memory read/write. Could you please help?
