SPRUEC6G: Bootloader for c645x Misunderstanding

William Martin

What is the purpose of the fifth bit in the CFGGP[4:0] to CFG[3:0] bits?  It mentions that its referred to as 5 bits to 4, and the 5th bit is unclear of what happens to it during boot-up of the processor. 

 

Thank you

    William,

    It just means that we allocated an extra bit to this boot configuration field. We wanted to make it clear that you will be using 4 bits, and refer to this as CFG[3:0].

    For safe and reliable operation, keep CFGGP[4] at 0.
