Starterware: MLO and BlinkLED put together to boot BBB from SD card

sonMEE

Tool/software: Starterware

Hi,

Using CCSV6 and StarterWare examples such as gpioBlinkLED produces a binary file. MLO file is resides in C:\ti\AM335X_StarterWare_02_00_01_01\binary\armv7a\cgt_ccs\am335x\beaglebone\bootloader\Release_MMCSD\MLO

How do I put these two files together and boot BBB from SD card.

Thanks

Hi Lali,

I'm using beaglebone black. The files gpioLEDBlink.bin is the result of compiling gpioLEDBlink.c. The file MLO is part of StarterWare..... /beaglebone/bootloader/Release_MMCSD/MLO.

Should I copy these two files to the boot sector of SD without any mingling, then boot the BBB board.?

Thanks

Hi Amin,

After format the disk, you have to follow these steps in( processors.wiki.ti.com/.../AM335X_StarterWare_Booting_And_Flashing ).

6 . After the formatting is complete, the card is ready to be populated with the files required.
7. The converted bootloader binary image(Bootloader binary image(boot.bin) appended with the TI Image Header) has to be renamed to "MLO" from "boot_ti.bin". The boot_ti.bin is created by building the bootloader in MMC/SD boot mode.
8. Similarly the converted application binary image has to be renamed to "app" from "<app_name>_ti.bin"
9. Copy both the boot loader image "MLO" and the application image "app" to the SD card.
10. Safely eject/remove the card from the host, unplug the card reader, remove the SD card. The SD card is ready for use on AM335x target.

:::::::::
First copy MLO file, after app ( file renamed).
