how to configure stm32l4r9i octospi for reliable hyperram operation
Hi, I have stm32l4ri-eval how do i configure the octospi interface to use the issi hyperam which is onboard.
Hello
As mentioned in the User Manual Table 44. The main board does not support Octo-SPI operation with PSRAM. No
workaround available. Refer to STM32L4Rxxx and STM32L4Sxxx device errata sheet.
For that in STM32L4R9I-EVAL B02, the ISSI IS66WVH8M8BLL-100BLI changed into ‘Not fitted'
Thank you.
