AM2434: Firmware valid flag

Hi Dominik,

I assume you asked two questions:

1. How to read/set the bit fields in the AM243x registers

2. How to reset the AM243x to trigger a bootloading.

For 1,  you can use the MACROs defined in C:\ti\mcu_plus_sdk_am64x_08_02_00_31\source\drivers\hw_include\cslr.h, such as CSL_FEXT and CSL_FINS.

For 2, you can use the CCS --> Run --> Reset --> System Reset to trigger a WARM RESET. it will trigger a bootloading session. If you want to trigger a WARM RESET in your application code by calling SOC_generateSwWarmResetMainDomain().

Best regards,

Hey Ming,

Great advice as always. Register writing seems to be fine.
However I was unable to use SOC_generateSwWarmResetMainDomain() in my code.

In SDK:

C:/ti/mcu_plus_sdk_am243x_08_02_00_31/docs/api_guide_am243x/group__DRV__SOC__MODULE.html 

there is not documentation on this function. Do I need to make any includes to use SOC_generateSwWarmResetMainDomain().
Other SOC funcitons are running fine when including soc.h.

Thank you for your advice and have a great day.

Dominik

Hi Dominik,

I am sorry. The SOC_generateSwWarmResetMainDomain() is a newly added SOC function. It will be released in MCU+ SDK 08.03.00 in a few days. You cannot find it in MCU+ SDK 08.02.00.31.

void SOC_generateSwWarmResetMainDomain(void)
{
/* Reset Ctrl belongs to partition 6 of the CTRL MMR */
uint32_t rstPartition = 6U;

/* Unlock CONTROL MMR registers */
SOC_controlModuleUnlockMMR(SOC_DOMAIN_ID_MAIN, rstPartition);

/* MAIN domain reset */
CSL_REG32_FINS(CSL_CTRL_MMR0_CFG0_BASE + CSL_MAIN_CTRL_MMR_CFG0_RST_CTRL,
MAIN_CTRL_MMR_CFG0_RST_CTRL_SW_MAIN_WARMRST,
0x6U);

/* Lock CONTROL MMR registers */
SOC_controlModuleLockMMR(SOC_DOMAIN_ID_MAIN, rstPartition);

/* execute wfi */
#if defined(__ARM_ARCH_7R__)
__asm volatile ("wfi");
#endif
}

Best regards,

Ming
