Linux/LINUXSDK-OMAPL138: OMAPL138

Part Number: LINUXSDK-OMAPL138

Tool/software: Linux

Hi,

I am having OMAPL138 platform based firmware, i am planning for firmware signing. My binary file size is 35 mb (firmware.bin) which composed of uImage and rootfs.img

My query is on signing firmware,

1. need procedure to sign the firmware.bin

2. API to acknowledge and accept the firmware in device (in uboot or anymeans)

If we sign the firmware using third party for eg: Nanoboot from Mocana, is it possible to acknowledge the firmware in uboot?

Kindly share ur thoughts in this.

Thanks in advance,

Muthukumar V

    Hi, Muthu,

    What Processor SDk are you using? Are you trying to do secure boot? I don't think secure boot is supported on OMAP-L138 device.

    Hi,

    I have the firmware which is 6 to 8 years back, and I am not aware of this Linux SDK Version used.

    Yep i am planning for secure boot, i have created signature part for this firmware by using trusted CA , now i am planning to validate it while boot-up.

    I have downloaded a user manual for secure boot for OMAP L1-x processor

    Can i follow up the manual for secure boot for my case?

    Thanks,
