Some AT88SC25616C-SU were written by IIC driver of Android system within the product.
I would like to ask why I encounter this message when programming.
Someone pointed out that maybe the MAC was not properly written. Therefore, the CERT programming was tried again step by step to ensure all processes were within their product spec. , and it still failed. To my understanding, it meant this crypto is not working properly as its own spec declared whereas I have other much more same chips are working well in the same firmware.
