Can you use both CS's for SDRAM on the STM32F7

I have an application where I need lots of ram, I have designed a board with both CS used

SDNE0 and SDNE1 along with SDCKE0/1.

When I init both chips in the HAL the board will crash, but either one will work, has this been tested because I don't see any other boards with 2 sdram chip...

Hi aldridge.nicholas,

It is a known issue related to the HAL drivers, but it has been fixed on the last release of the STM32cubeF7 package (1.4.0)

Refer to this [DEAD LINK /public/STe2ecommunities/mcu/Lists/STM32Java/Flat.aspx?RootFolder=/public/STe2ecommunities/mcu/Lists/STM32Java/stm32cubemx%20init%20SDRAM%20in%20STM32F429NI&currentviews=42]thread for more details.
