I am using IMX93 EVK where I required to reduce cpu frequency of A core which is currently 1600MHz.
I want to reduce it up to 200MHz,
Earlier for IMX8ULP EVK I followed below method and I was able to control frequency on A core with accessing appropriate resisters
# Switch a35 to FRO 192 MHz /unit_tests/memtool -32 0x292c0014=0x08000000 # Set PLLEN to 0 /unit_tests/memtool -32 0x292c0500=0x03000000 # Read and set the division and multiplication factors /unit_tests/memtool -32 0x292c0014 1 /unit_tests/memtool -32 0x292c0510 1 # Set PLLEN to 1" /unit_tests/memtool -32 0x292c0500=0x03000001 # Switch a35 to PLL2" /unit_tests/memtool -32 0x292c0014=0x18000000 mhz
I checked reference manual of IMX93, but I am not able to get resistor by which I can control clock,
Can anyone guide me on this?
