TDA4VM: Precise Boot time measurement

Hi,

Now I have a test, but the data is different from the official data, and there is a lot of difference：

The reset pin:

Test result：


From Reset to the frist line code in sbl_main.c, It take 54ms. This is obviously abnormal. Is there any way to reduce the time it takes for the reset signal to reach the first line of sbl code?

MCU_PROZ_OUT to MCU_RESETSTATz it take 0.63ms. how to test it? 

Please refer to the steps below.let us know If this helps.

******************************Boot Performance test procedure************************
step 1:

Build sbl_boot_perf_cust_img_mcu1_0_release.tiimage by using the following command.

    make BOARD=<board_name> sbl_boot_perf_cust_img  -sj
    you can find the image in <pdk install path>/pdk/packages/ti/boot/sbl/binary/<board_name>/cust/bin/
    

step 2:

Build sbl_baremetal_boot_perf_<board_name>_mcu1_0TestApp_release.appimage by using the following command

    make BOARD=<board_name> CORE=mcu1_0 sbl_boot_perf_test -sj
    you can find the image in <pdk install path>/pdk/packages/ti/boot/sbl/example/k3MulticoreApp/binary/<soc_name>/

step 3:

Change the boot switch settings to UART bootmode.
   
step 4:

Flash uart flash programmer (below commands are suitable for linux PC)

sudo <path to uniflash tool>/uniflash_8.0.0/dslite.sh --mode processors -c /dev/ttyUSB* -f <path to uniflash tool>/uniflash_8.0.0/processors/FlashWriter/<board_name>/uart_<board_name>_flash_programmer_release.tiimage -i 0

example:
 sudo ./dslite.sh --mode processors -c /dev/ttyUSB1 -f  <path to uniflash tool>/uniflash_8.7.0/processors/FlashWriter/j721e_evm/uart_j721e_evm_flash_programmer_release.tiimage -i 0
 
step 5:

Flash sbl_boot_perf_cust_img_mcu1_0_release.tiimage at 0x0

sudo <path to uniflash tool>/uniflash_8.0.0/dslite.sh --mode processors -c /dev/ttyUSB* -f <pdk install path>/pdk/packages/ti/boot/sbl/binary/<board_name>/cust/bin/sbl_boot_perf_cust_img_mcu1_0_release.tiimage -d 3 -o 0
 
 example:
sudo ./dslite.sh --mode processors -c /dev/ttyUSB1 -f <pdk>/packages/ti/boot/sbl/binary/j721e_evm/cust/bin/sbl_boot_perf_cust_img_mcu1_0_release.tiimage -d 3 -o 0


step 6:

Flash tifs.bin at 0x80000

    for j721e : sudo <path to uniflash tool>/uniflash_8.0.0/dslite.sh --mode processors -c /dev/ttyUSB* -f <pdk install path>/pdk/packages/ti/drv/sciclient/soc/V1/tifs.bin -d 3 -o 80000
 
example:
sudo ./dslite.sh --mode processors -c /dev/ttyUSB1 -f <pdk>/packages/ti/drv/sciclient/soc/V1/tifs.bin -d 3 -o 0x80000
    
step 7:

Flash sbl_baremetal_boot_perf_<board_name>_mcu1_0TestApp_release.appimage at 0x100000

    sudo  <path to uniflash tool>/uniflash_8.0.0/dslite.sh --mode processors -c /dev/ttyUSB* -f <pdk install path>/pdk/packages/ti/boot/sbl/example/k3MulticoreApp/binary/<SOC>/sbl_baremetal_boot_perf_test_<board_name>_mcu1_0TestApp_release.appimage -d 3 -o 100000
    
example:
sudo ./dslite.sh --mode processors -c /dev/ttyUSB1 -f <pdk>/packages/ti/boot/sbl/example/k3MulticoreApp/binary/j721e/sbl_baremetal_boot_perf_j721e_evm_mcu1_0TestApp_release.appimage -d 3 -o 0x100000
    
step 8:

Flash NOR spi pattern

    for j721e : sudo <path to uniflash tool>/uniflash_8.0.0/dslite.sh --mode processors -c /dev/ttyUSB* -f <pdk install path>/pdk/packages/ti/board/src/flash/nor/ospi/nor_spi_patterns.bin -d 3 -o 3FE0000
    
 example:   
 sudo ./dslite.sh --mode processors -c /dev/ttyUSB1 -f <pdk>/packages/ti/board/src/flash/nor/ospi/nor_spi_patterns.bin -d 3 -o 3FE0000
        
 
 step 9:
 
/dev/ttyUSB* will be the second instance of MCU uart.


step 10:

Change the boot switch settings to OSPI boot.

step 11:

Power ON the board

step 12:
If you get some logs and All tests passed at the end on MCU uart then you can mark this test as passed.


step 13:
PASS string : Boot Performance test has passed

Hi，Karthik

It take 37.55ms。

But in fact, I need to test by pulling IO on the evm board. Is there any way to do this?

Hi, Karthik

which test point on tda4vm evm board is MCU_PROZ_OUT ?
which test point on tda4vm emv is MCU_RESETSTATz ?
I will use  Oscilloscope and test by myself.

Eason

Hi, expert:

Can Ti expert  give some suggestions which I can accurately measure the startup time from power on to sbl from an oscilloscope?

I'll look into this more closely and get back to you.
