Hi,

Can I get some guide to make a bootable sdcard for J721E EVM?

I used a PSDK ver7.1 and I've checked the user guild in Bootloader(SBL)/J721E SBL/Boot Modes/Booting Via SD Card.

In there,

Preparing the SD card

To boot the target the SD card should be bootable. Follow the steps at Creating bootable SD card in windows or Creating bootable SD card in Linux.
To update the SBL with a newer version, copy the sbl image (sbl_mmcsd_img_mcu1_0_release.tiimage) to the SD card. Rename it to tiboot3.bin
Copy the generated application image(*.appimage or *.appimage.signed) to the SD card. Rename it to app

Click 'Creating bootable SD card in Linux, then this link is opened.

But, I can't find the create-sdcard.sh file.

Best regards

Yongsig.

I tried as below, but I can't see any messages from MCU uart terminal.

Creating SD card
1. >> cd psdk_installed_path
2. >> sudo ./psdk_rtos/script/mk-linux-card.sh /dev/sdc
Copy sbl imaged to BOOT directory in SDcard
1. >> cd /pdk_jacinto_01_01_00_45/packages/ti/boot/sbl/binary/j721e_evm/mmcsd/bin/
2. >> cp -rf * /media/yongsig/BOOT
Change boot file name
1. >> cd /media/yongsig/BOOT
2. mv sbl_mmcsd_img_mcu1_0_release.tiimage tiboot3.bin
Configure the switches on EVM
1. setting to SD boot mode
Insert SDcard and Power-up

Is there a wrong step??

or should I open mcu uart like 'MCUSW_UART_ENABLE' in mcusw ?

Best regards

Hi Yongsig,

The MCUSW_UART_ENABLE flash should be true by default.

The UART you should be looking at is the 1st UART which comes in when you connect to the J43 connector on the EVM.

Karan
