I have some bare-metal boot code written for A53, and now I have to use a35. Is the code also usable for A35?
Without knowing your code, how shall anyone judge? But I guess it contains A53 specific stuff, so likely: No.
In the "DAI0527A_baremetal_boot_code_for_ARMv8_A_processors.pdf", it is said that it's usable for Cortex-A53, Cortex-A72, and Cortex-A73. Is it also usable for A35?
Why not just try?
Ok, I will have a try!
