External flash memory for mt7697


#1

I’m building a firmware for the mt7697 with BLE/Wifi.
It looks like my .bss region wont fit inside my SYSRAM, which has 256 kb.
How do I enable the external flash memory so I can use both stacks (bluetooth and wifi?)


#2

You might want to ask on the MediaTek forum


#3

Ok.
But have you guys done something on having both wifi and bluetooth in mt7607?


#4

Are you using mt7697 or mt7697d?


#5

(sorry typo in previous message. mt7607 -> mt7697)
Mangoh red schematics shows MT7697.


#6

It is mt7697d in the bom, 7697 will not work for Bluetooth, not enough memory


#7

If you’re talking about the bom found here, it says MT7697.

Still, if the MT7697 does not have enough memory, I think that was the reason you guys put the external flash, isn’t it? So, we just need to manage to use the flash.


#8

Yes, we prove a quad spi memory on mangoh red for that

Correction on above, mt7697 is the correct part. I was thinking of mt7687.
