IAC exceptions when launching M33 core

[nielsenni101]

Hello,

I am trying to load an .elf file on the M33 core on my stm32mp257f processor. When I launch the remote core using remoteproc I get the following errors.

hey currently i am working on stm32mp257dak3 on myir myc-ld257 board  in which i want to access RCC of gpiog for i2c3,  but i am enable to access it as soon as i try to access without resource manager it shows me "root@myd-ld25x:~# echo start > /sys/class/remoteproc/remoteproc0/state

I/TC: Halting CPU 0" this error and my linux gets crash (on board linux not in my laptop)

but when i uses resource manager " if (ResMgr_Request(RESMGR_RESOURCE_RIF_RCC, RESMGR_RCC_RESOURCE(96))

== RESMGR_STATUS_ACCESS_OK) {

__HAL_RCC_GPIOG_CLK_ENABLE();

}" this condition not gets true and i came out of if() and ultimately rcc is not enable

so tell me how to solve this problem?
