TDA4VM: Try to boot by SBL, but failed, and Try to debug sbl but also failed

7558.img.zip

This is my images. Could you help me to 

verify it?

This does not look like ROM location, it does seem it is running from SBL, can you put while (1) in the main function, then connect CCS and check where it crashes?

Brijesh

Hi Brijesh,

I had put a while(1) in main function:

But it do not work.

Hi eason,

What do you mean by it do not work? Doesn't it go to main function? Are you able to connect CCS and check where it is stuck? 

Also are you checking this on EVM? 

Regards,

Brijesh

Hi Brijesh,

I mean it does not go to main function, I can connect CCS but i can't find the problem.
I try to boot by sbl_mmcsd_img , but it does't work. The serial port does not have any output.(None of the six serial ports have output）

There no debug info.

Hi eason,

But on the scripting console window, i think you are loading launch.js script, is it the case? Then this javascript loads the sciserver on the mcu1_0, and does not load SBL.

You dont need to run this java script, just copy SBL, tifs and application to run on the SD card's BOOT partition and use it on the board. You should see some uart messages once while loop is unblocked.

Brijesh

Hi, Brijesh

I had try your method:

But I don't see any messages (None of the six serial ports have output).

Regards,

Eason

please confirm that while loop is removed or atleast is unblocked.

Also please connect CCS and check where SBL is now?

Brijesh

Hi Brijesh,

Following is my steps:
1) copy SBL、tifs.bin、app to SD boot partition.

2) connect all uart.

3) power on the board

4) connect CCS and connect mcu1_0:

but there are no message output from the uarts.

and the muc1_0 always on "F10801C0 cpsie aif"

Hi Brijesh,

Any update here?

But ROM is not now recognizing SBL. Are sure that you are copying correct appimage of SBL? Also are you using GP silicon or HS silicon? 

Hi Brijesh,

I copy the sbl_mmcsd_img_mcu1_0_release.tiimage to sd boot partition as tiboot3.bin and make a checksum by md5sum
I asked the purchasing staff and he said this is GP silicon.

How to distinguish whether this development board is GP or HS?

Regards,

Eason

ok, then, is the bootmode correctly setup for SDMMC boot mode? 

Hi Brijesh,

Boot mod:
sw8[1-8]: 1000 0010
sw9[1-8]: 0000 0000

Hi Brijesh

Do you have any suggestions to fix it?

Eason

Hi,

The only other thing is to check it on EVM, i can check it only next week.

Hi Eason,

Not yet, i will not be able to check it on EVM this week, i will get back to you by early next week.

Regards,

Brijesh

Hi Brijesh,

Can you help to check this case this week?

Regards,

Eason

Hi Eason,

Sure, will try.

Brijesh

Hi Reijesh,

Do you have any suggestions to check this?

Regards,

Eason

Hi Eason,

Have you tried building and running SBL from the released SDK8.1? It should work fine, as it is part of release and validated on EVM. 

Regards,

Brijesh

Hi Beijesh,

I have already tried.  The topmost compressed file is compiled from SDK 8.1(7558.img.zip), but it cannot be booted.

So, Could you provide a boot image  "sbl_mmcsd.img"? I would like to try booting with it, and then you can try booting with the image file from the compressed package I mentioned earlier (booting from an SD card). This way, we can cross-validate our results.

Eason

Hi,

Are you trying it out on EVM? 

Regards,

Brijesh

Hi Brijesh,

yep. I trying it out on EVM.

Regards,

Eason

ok, let me check it on EVM.

Regards,

Brijesh

Hi Brijesh,

How did the test go? Was it able to boot on the EVM? What should I do differently to make it boot on my end?

Hi Brijesh,

Any update here?

Regards,

Eason

Hi Eason,

Not yet, i will post the update on this friday.

Brijesh

Hi Brijesh,

Could you give me any suggestions today？

Hi,

SBL in SDK8.1 works fine on EVM. I build it for GP device, copied SBL, tifs and one sample example for udma memory copy and i could see below log from SBL.

I am also attaching the three files that i used on EVM, can you please try it out on your board?

08.01.zip

Brijesh

Hi Brijesh,

I have tried on my evm, but it do not work, no sbl-log output from mcu1_0 Serial, meanwhile, I use different SD-Card and different TI-TAD4-EVM，there is also no output from mcu1_0 Serial.

Regards,

Eason

Hi Eason,

Can you please check and confirm that you are using correct UART part and these files are copied correctly and also board is in the SD boot mode?

Regards,

Brijesh

Hi Brijesh,

Glad to tell you that this can boot successfully, can you tell me, this is how tiboot3 compiles? What changes did you make under SDK 8.1?

Regards,

Eason

Hi Eason,

I have not done any changes in the SDK. I just run below two commands from the ti-processor-sdk-rtos-j721e-evm-08_01_00_13\pdk_jacinto_08_01_00_36\packages\ti\build folder and copied generated SBL file (ti-processor-sdk-rtos-j721e-evm-08_01_00_13\pdk_jacinto_08_01_00_36\packages\ti\boot\sbl\binary\j721e_evm\mmcsd\bin\sbl_mmcsd_img_mcu1_0_release.tiimage) as tiboo3.bin file to the sd card's boot partition.

1, make pdk_libs -s -j4 BOARD=j721e_evm 

2, make sbl_mmcsd_img -s -j4 BOARD=j721e_evm

Hi Brijesh,

Thank you very much for your support over the past three weeks. Wishing you a happy life.
