Kit d'evalution FPGA et STM32

As far as I understand it M0 and M1 are the configuration pins on your fpga. So read the above again, while keeping in mind that M1=PD means 'pulldown M1 aka M1=0' and M1=PU means 'pullup M1 aka M1=1'.

Put another way, no you cannot do this from impact. M0 and M1 are hardware pins so you will probably have to change some jumper settings. At the very least follow the M0/M1 in your schematics to see how they are connected.

from schematics it is clear than in order to use the flash you need to :

1. COJP200 is in "on"
2. set this 2 i/o pins from the st controller :
------------------------------------------
SLAVE_SER_OE => "1" for SPI FLASH
FLASH_OE => "0" for SPI FLASH

since they didn't put any hw option to control SPI FLASH,SPI FLASH you must initilise the ST to assert this signals.

if i understand that i must
1) initialise in the MCU st controlloer the two pins of FLASH_OE and slave_SER_OE : FLASH_OE == 0 and slave_SER_OE == 1 and i load my project in STM
2) after that i load the project in SPI to activate my FPGA ?

ye, check D202 led lights.
if not i would advise you to connect a push button to your fpga "PROG" pin.
so you will need to solder it to a pushbutton.

this will enable you to confugre fpga without the ST interveening.

jp200 should be "on" i don't konow what's the label on the pcb but i guss it will show '1' and not '0'.
if the led "DONE" lights it's fpga load is ok.
----------------------------------------------
basically your SPI flash should be read automatically on start - up by the fpga. so you don't have to use "PROG"
----------------------------------------------
seperating the ST is as i told you

SLAVE_SER_OE => "1" for SPI FLASH
FLASH_OE => "0" for SPI FLASH
INIT should be decaqlared as input - so you don't drive it.
-----------------------------------------------------
after you do all this settings. you can control "PROG" to configure FPGA manually from SPI flash.
so you can connect this signal to a push button , you can try to solder a wire from IC201/3 to Test button SW200.
