Hope this note find you all well in 2019.
As per Arrow FAE recommendation we used migration path Flash chips on our boards, but we are having some technical issues. I will really appreciate if you could please help and resolve this issue for us.
We made custom board based of 440EPX Sequoia board with S29GL512P flash in year 2010. We were able to get those boards working all these years. Now those S29GL512P flash chips are obsolete and so we used the migration path chip S29GL512S in our latest boards. We tried to use the same Uboot, etc on these boards and they don’t work.
We really appreciate if you could help us debug and resolve this problem.
Best regards
Madhu
