RTOS/PROCESSOR-SDK-AM335X: Application fails to start from SD card

rafal Borkowski

Tool/software: TI-RTOS

Hi,

I'm trying to run my application from sd card. When I'm runnig debug via JTAG befor starting my application I run this script AM335x_PRU_ICSS.gel. After I copy every code similar to C I have to convert this code to C:

GEL_MemoryFill(0x4a300000, 0, 16*1024, 0x0, 0xC);
GEL_MemoryFill(0x4a310000, 0, 12*1024, 0x0, 0xC);

How do I do it? Please help me.

Rafal,

Have you created the app image from your .out file and followed the instructions here to boot from an SD card?

Yes I did I even use the option with ENABLE_PRU=yes. The only thing missing in my application is this GEL_MemoryFill(0x4a300000, 0, 16*1024, 0x0, 0xC); and
GEL_MemoryFill(0x4a310000, 0, 12*1024, 0x0, 0xC); I need to write something under this adresses but I don't know what exactly GEL_MemoryFill do becouse it is diffrent then memset. Can you translate it to "C". Or maybe I need to create diffrent MLO file

Rly there is no solution to my problem? Everything works almost fine but I need to do GEL_MemoryFill(0x4a300000, 0, 16*1024, 0x0, 0xC); and GEL_MemoryFill(0x4a310000, 0, 12*1024, 0x0, 0xC); this in my code but i cant translate it to C. Can you help me?

Rafal,

Please refer to the SBL code at C:\ti\pdk_am335x_1_0_9\packages\ti\starterware\bootloader\src\am335x\ sbl_am335x_platform.c to add you can add following code into his application or modify the SBL.

static void PRU_ICSS_PRCM_Enable(void)
{
                const void * prussPruDramBase = (void *)SOC_PRU_ICSS_DATA_RAM0;
                const void * prussSharedDramBase = (void *)SOC_PRU_ICSS_SHARED_RAM;
                PRU_ICSS_PRCM_Reset();
                *((unsigned int*) (SOC_CM_PER_REGS+0xE8)) |= 0x2;
                PRU_ICSS_PRCM_Reset();
                memset((void *)prussPruDramBase, 0, (16*1024));
                memset((void *)prussSharedDramBase, 0, (12*1024));
}

static void PRU_ICSS_PRCM_Reset(void)
{
                *((unsigned int*) SOC_PRM_PER_REGS) |= 0x2;
                *((unsigned int*) SOC_PRM_PER_REGS) &= 0xFFFFFFFD;
}
