“Unhandled fault: external abort on non-linefetch (0x1008) at 0xa1000000” in mx25l25635g

[aaronkuo]

Hi NXP,

We use the same code in mx25l51245g and mx25l25635g QSPI Flash

It can work normally mx25l51245g, but there are error messages “Unhandled fault: external abort on non-linefetch (0x1008) at 0xa1000000” in mx25l25635g

Please help us to solve this issue
