1.How to burn PBL in SOC?

Hi Everyone,

I have designed a custom board using Qualcomm 410e.
I’m facing some issues with the bootloader. Please help me out.
These are my questions:

  1. How to burn the Primary bootloader into the SOC.
  2. How to burn Secondary bootloader into EMMC.
    I have added a JTAG connector but I can’t find the steps for the primary and secondary bootloader process.
    Hoping to hear from you soon.
    Thanks in advance.
