Hello, in my project i need to have more SDRAM than original 4M*16b.
So i ordered 32M x 16b ISSI IS42S16320d-7TL that fit's inside the same footprint, and i soldered single jumper cable to PG2 as well as modified GPIO init code for this pin.
But what else do i need to modify in order to run this memory ?
In examples i runned SDRAM test code that checks all SDRAM but even
FMC_SDRAMInitStructure.FMC_ColumnBitsNumber = FMC_ColumnBits_Number_10b; ( changed from 8b to 10b)
/* Column addressing: [11:0] */
FMC_SDRAMInitStructure.FMC_RowBitsNumber = FMC_RowBits_Number_13b;//FMC_RowBits_Number_12b; (this is also changed to 13b from 12b)
Is that it, or should i do more ? ( problem is that shorting PG2 to ground, example did not generate any problem)
