STM32H7S7 XiP with Hyperbus Flash S26HS01GTGABHB030

bcompter · ‎2026-02-10

I am working with a custom board populated with an STM32H7S7L8H6H and a hyperbus flash S26HS01GTGABHB030 connected on XSPI1.

My intent is to execute in place on the hyperbus flash but have not been successful thus far.

Interestingly I cannot select CONFIG_8LINES for the Memory 1 configuration in CubeMX.

Hello @bcompter

After investigation, CONFIG_8LINES should be available in Hyperbus mode. It seems that this is a bug on the CubeMX side. An internal ticket has been raised to the dedicated team for fix. (Ticket 227131 This is an internal tracking number and is not accessible or usable by customers.)
I appreciate your valuable contribution

Hello @bcompter

As mentioned in the description, CONFIG_8LINES is only available when XSPI is in OCTO SPI mode.

Setting XSPI1 to Octo SPI does not then allow Memory Type to be set to Hyberbus.
