Discussion - EVE / FT810 can´t get QSPI working
« on: February 14, 2020, 04:07:56 PM »
Hi everyone,
I can´t get my FT810 in QSPI Mode running. In single mode it´s perfectly working but as soon as I change to qspi nothing works.
I checked the entire data stream with an logic analyzer. For me it seams, that in quad, the ft810 never starts to send any data back.
The SPI_WIDTH register is correct addressed with the needed paramter (0x2 for qspi 1 dummy, 0x6 for qspi 2 dummy), thats what I still can see with the LA becuase it´s in single mode.
The register I´m trying to read it REG_ID because for my unterstandig this should be a good reference to verify if qspi reads proper results.
It´s approx 7us from the last address byte to the receive procedure of my MCU, but I can´t see any usefull data comming form the ft810.
Does some have have FT810 or BT816 running in QSPI?
Im using a EVE4.5 GUI with the corresponding EVE Framework.
Thanks for any help you guys can provide!
Cheers!
