Hi Widic,

You need to check in your code where exactly you are accessing 0x182d0510.

I can not understand this.
Can you be more specific?

Hi Widic,

You should put a while loop on a volatile variable in the code where you have added MCSPI code.
Then after booting you can connect CCS and single step through code to see where exactly this particular access is happening.

Hi Widic,

We have only 32 MB of NOR flash connected on EVM. Hence error will be generated even though it falls in GPMC space.
Are you able to locate the code which leads to this access?

Hi,

You should build in debug mode and then a step by step debug.
Unless you can specify what is the error I won't be able to help.

Hi,

I haven't heard back from you, I'm assuming you were able to resolve your issue.
If not, just post a reply below (or create a new thread if the thread has locked due to time-out).
