Hi,

Vishal Kumar said:

as per log SPI probe is failing, Not getting why. 
Let me know if anything missing.

Our Expert is OoO, Please excuse the slight response delay.

Hello Tarun,

Can you share the documentation that you have referred & the actual steps you followed?
What is the boot flow that you are planning to use?
OSPI is your boot media?

Steps Followed:

- I'm trying to load SBL files to OSPI-flash from sd-card SPL boot.

- Inside sd-card boot partition I've a folder named sbl inside which I'm storing below 3 files.

- tiboot3.bin(OSPI), app($(MCU_SDK_PATH)/tools/boot/linuxAppimageGen/board/j722s-evm/linux.appimage.hs_fs) and u-boot.img($(MCU_SDK_PATH)/tools/boot/hlos_prebuilt/j722s-evm/linux/u-boot.img) to OSPI-FLASH in u-boot terminal.

- First boot the SPL and stop at u-boot terminal and load the sbl folder files to OSPI flash

- Steps in u-boot terminal:

sf probe
sf erase 0x0 80000
sf erase 0x80000 100000
sf erase 0x280000 0x400000
fatload mmc 1:1 ${loadaddr} sbl/tiboot3.bin
sf update ${loadaddr} 0x0 0x${filesize}
fatload mmc 1:1 ${loadaddr} sbl/app
sf update ${loadaddr} 0x80000 0x${filesize}
fatload mmc 1:1 ${loadaddr} sbl/u-boot.img
sf update ${loadaddr} 0x280000 0x${filesize}

- Power off and change boot mode to OSPI-flash

- The logs are attached in previous message.

OSPI flash (SW2.1 is OFF) is boot media for the SBL

Hello Tarun,

To begin with please try to use the SPL boot flow. The 9.2 SDK has issues with ospi boot:

Here is the FAQ:

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1352670/faq-j722sxh01evm-how-to-enable-ospi-nand-nor-boot-on-9-2-linux-sdk

Please follow that and let me know if you can get to U-Boot prompt.

Best regards,

Keerthy

I followed the link, and able to get U-Boot prompt from NOR Boot.

Vishal Kumar said:

I'm trying to run linux-appimage(linux.appimage.hs_fs) SBL application in OSPI-NOR

• tiboot3.bin at 0x0 of OSPI-NOR
• app at 0x80000 of OSPI-NOR
• u-boot.img at 0x280000 of OSPI-NOR

Now I need to load these 3 into NOR flash (SBL boot). Can you please tell me how to continue.

Regards,

Tarun C

Hi Vishal,

You should now compile the combined app image with the above generated binaries.

Best regards,

Keerthy 

Hi Keerthy,

Now I'm able to get till u-boot terminal in OSPI-NOR flash using SBL mode.

My use case is to load linux Image from NOR flash to RAM.

When I run sf probe in u-boot terminal board crashes, logs are attached below.

Tarun,

Check the dip switch settings for ospi nor boot.

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1352670/faq-j722sxh01evm-how-to-enable-ospi-nand-nor-boot-on-9-2-linux-sdk

Regards, 

Keerthy

Hi Keerthy,

dip switch settings I'm using is for ospi-nor flash only.

Hi Vishal,

Then make sure that you have integrated the patch with the U-boot that is working for you already. You are able to flash with the changes that i suggested & that means sf probe worked.

Vishal Kumar said:

I followed the link, and able to get U-Boot prompt from NOR Boot.

 I believe here the sf probe should have worked to flash binaries to NOR.

- Keerthy

Hi Keerthy,

I've flashed binaries to NOR flash and able to get into u-boot terminal of SPI-NOR flash.

sf probe is working in u-boot terminal of sdcard but not in u-boot terminal of spi-nor flash.

Vishal Kumar said:

My use case is this.

Can you please tell me the issue.

Tarun C
