TMS570LC4357: Example code for enabling low power mode in microcontroller TMS570LC4357

Thanks jadadish

I flashed below code to put ECU in low power mode (snooze)

/** - Setup GCLK, HCLK and VCLK clock source for normal operation, power down mode and after wakeup */
systemREG1->GHVSRC = (uint32)((uint32)SYS_LPO_HIGH << 24U)
| (uint32)((uint32)SYS_LPO_HIGH << 16U)
| (uint32)((uint32)SYS_PLL1 << 0U);

/* turn off all clock sources except LF LPO */
systemREG1->CSDISSET = 0xEF;

/* turn off all clock domains except RTICLK */
systemREG1->CDDISSET = 0xFFBF;

Now ECU is not waking Up at all.

I am getting above error "Unable to access DAP"

what i can do to wake Up ECU again?

Adding information to this issue

I am unable to flash the ECU.

I am getting below error

currently ECU consume around 120mA current.

Hi Manoraj,

Can you please attach your complete project once, i will try to debug it on my end.
