Part Number: TMDSEVM572X
Tool/software: TI-RTOS
Hi,
I an using GP AM572x SDK:pdk_am57xx_1_0_5
TIRTOS: processor_sdk_rtos_am57xx_3_02_00_05
I want to change operating frequency from OPP_NOM to OPP_HIGH. how can i do this?
I tried with following change in code but it doesn't happen.
boardCfg = BOARD_INIT_PINMUX_CONFIG |
BOARD_INIT_MODULE_CLOCK | BOARD_INIT_UART_STDIO | BOARD_INIT_PLL_OPP_HIGH;
Board_init(boardCfg);
This gave me run time error.
Thanks,
Anjana Pathak
Anajana,
Please indicate what runtime error did you see with BOARD_INIT_PLL_OPP_HIGH ?? OPP as Eric explained is a combination of higher clock and PMIC voltage so increasing to OPP_HIGH without increasing the voltage could result in runtime issues but you should have been able to do this for a short period of time. Note that the board library for GP EVM only sets up the clock for OPP_HIGH, the voltage will need to be changed using PM LLD.
Regards,
Rahul
PS: Refer to pmrtos_measurement example where this has been demonstrated for AM335x and AM437x. We plan to extend this for AM57x but this is currently not available out of the box.
Hi Rahul,
Run time error is related to ADP error (CortexA15_0: Unhandled ADP_Stopped exception 0x20023) and it comes when i put a break point on board_init(boardcfg). else it dose not execute the function below boar_init() which is CSL_xbarMpuIrqConfigure(.....) and hang off. Please see into the file attached, this is the file in which i am modifying for HIGH_OPP. How can i see the clock being set at higher clock?

and as Eric said "change GEL file to run at OPP_HIGH for a short period of time". This means this high clock speed cannot be use throughout or for long period? and which and where in gel file need to modify?
Thanks,

Hi,
In ccsv7\ccs_base\emulation\boards\am572x\gel\AM572x_startup_common.gel, AM57xx_EVM_Initialization() function, replace AM572x_PRCM_Clock_Config_OPPNOM() with AM572x_PRCM_Clock_Config_OPPHIGH() for a quick try.
Regards, Eric
there are multiple ways of testing OPP_HIGH.
Option 1: In the GEL, there is option implemented to set the clocks to OPP_HIGH:
Option 2: The secondary bootloader (SBL) also has this option. If you build SBL using
make all BOARD=idkAM572x SOC=AM572x BOOTMODE=mmcsd OPPMODE=opp_high
There are two pins on the AM572x that can be used to route the MPU Clock out. Refer to diagram on Page 522 in TRM to see how the clock can be observed.
