TDA4VM: how to set boot address, OSPI+SBL boot.

Hi,

You can change these addresses in the SBL at PDK\packages\ti\boot\sbl\src\ospi.

how can i set to let device boot from A or B ?

You have two options to let the device boot from either of the side:

One, define a macro in the SBL based on which side A and side B can be configured and define the value of that macro during build.

Second, you can use the same macro but decide it's value during run time by using some hardware connection like a GPIO input.

HI, 

I use command to flash  file sbl_cust_img_mcu1_0_release.tiimage to address 0x0, and the rom code can load sbl_cust_img_mcu1_0_release.tiimage from address 0x0.

when i flash sbl_cust_img_mcu1_0_release.tiimage to address 0x10000, how to set the rom code load sbl_cust_img_mcu1_0_release.tiimage from 0x10000?

==>cmd:

dslite.bat   --mode processors -c COM8 -f  C:\Users\chenwenyu\Desktop\sbl_bootfiles\sbl_cust_img_mcu1_0_release.tiimage  -d 3  -o   0 (side A)

dslite.bat   --mode processors -c COM8 -f  C:\Users\chenwenyu\Desktop\sbl_bootfiles\sbl_cust_img_mcu1_0_release.tiimage  -d 3  -o  10000 (side B)

Hi,

It is not possible to changes the addresses that ROM uses for booting. You can modify the addresses for other images by modifying the SBL as mentioned previously. But SBL can be flashed only at 0x0.

HI, Parth Nagpal:

 if update software, sbl_cust_img_mcu1_0_release.tiimage need to be updated?

for example, software update from PDK 7.3 to PDK 8.0,    file  sbl_cust_img_mcu1_0_release.tiimage need to be updated? 

Thanks!

Hi,

There are not much changes in SBL from PDK-7.3 to PDK-8.0, but it is strongly recommended to use the SBL from corresponding PDK release.

HI,Parth Nagpal:

#SBL Image
C:\ti\uniflash_7.0.0\dslite.bat --mode processors -c COM8 -f C:\Users\chenwenyu\Desktop\sbl_bootfiles\sbl_cust_img_mcu1_0_release.tiimage -d 3 -o 0
#SYSFW BIN
C:\ti\uniflash_7.0.0\dslite.bat --mode processors -c COM8 -f C:\Users\chenwenyu\Desktop\sbl_bootfiles\tifs.bin -d 3 -o 80000
#Boot App

in ospi+sbl boot mode, sbl_cust_img_mcu1_0_release.tiimage image load tifs.bin , i wander the address 80000 how can be get by  sbl_cust_img_mcu1_0_release.tiimage ?

thanks!

Hi,

These addresses are defined in the PDK\packages\ti\boot\sbl\src\ospi\sbl_ospi.c

HI, Parth

"sbl_cust_img_mcu1_0_release.tiimage"  is released by TI.

when i modified the address 0x80000 to 0x100000,  and compile code.  how "sbl_cust_img_mcu1_0_release.tiimage"  can get the address 0x100000 ?

thanks!

#Boot App

This command flashes tifs at offset address of 0x80000. This address depends on the offset address we provide in the SBL. So, when you modify the SBL to take 0x100000 address instead of 0x80000, then the SBL will look for tifs at address of 0x10000 and the command should be modified to as

C:\ti\uniflash_7.0.0\dslite.bat --mode processors -c COM8 -f C:\Users\chenwenyu\Desktop\sbl_bootfiles\tifs.bin -d 3 -o 100000
