AWR1843:AWR1843: Compatible QSPI serial NOR flash for AWR1843

Dear Jun - 

Thanks for the post and welcome to E2E! 

Please see this application note, which shows parts we have tested.

The paragraph in-between the tables on pages 3 and 4 implies that flash variants are most likely interchangeable across variant usage, and the GD25B64C was tested with a newer variant from our portfolio as seen in Table 2-3 and you have already used another variant yourself successfully, so should be OK, as long as you check QE bit from the Flash vendor. 

Looks like the one we tested is larger version what you are looking at using now.
