PROCESSOR-SDK-J7200: Booting Linux with prebuilt binaries on J7200

Jonas Mohrs

Part Number: PROCESSOR-SDK-J7200

Tool/software:

Hello,

I am trying to boot into Linux on an J7200 device.

The primary bootmode of the device is OSPI, the secondary boot mode is EMMC.

I am trying to flash the prebuilt binaries into OSPI but I do not see any output and the device starts booting from EMMC.

Here are the files I am flashing into OSPI:

sbl_ospi_img_hlos_mcu1_0_release.tiimage at addr 0x0

tifs.bin at addr 0x80000

combined_opt.appimage at 0x100000

I do not see any printouts on the serial console and the device starts booting from the 2ndary boot device.

Any suggestions?

Thank you in advance.

Hello Jonas,

Few questions:

Which SDK version are you using?
Is this a custom board?
If it's a custom board which ospi flash part are you using? Is this same as the one on EVM?. If not you will have to do some custom changes for ospi but to work.

I am assuming that you are using MCU UART too check the logs.

Best Regards,

Keerthy

Hi,

its the newest SDK version: 10.01

Yes it is a custom board, I am not aware of any OSPI flags, could you please point to the proper documentation?

Thank you in advance.

Hi Jonas,

I meant custom flash part. Based on the flash used on your custom board we will need to make some changes.

Hi,

sorry I completely missed that part.

We have a different DDR after adjusting that worked.
