Hi Team, I am working on STM32U5A9J-DK for one of our applications interfaces with an Octal flash via Octal SPI. we were able to communicate and do the flash operations Read write using the SDR mode . Now to achieve the DTR mode from STM32U5a9 end ...

Hi Team, We are working on STM32U5A9J-DK for one of our application interfaced with Octal SPI Flash.We needed to acheive RWW operation which is supported by our Flash chip and we have used OSPI1 and OSPI2 in multiplexed mode but we are controlling Ch...

Hi @Tesla DeLorean Sorry for the delayed reply.We are using STM32U5A9J-DK board. The Macronix chip has been replaced with ISSI octal flash chip.Right now for SDR mode we are using Micron type in our settings where we are able to perform Read,Write E...

Hi @Tesla DeLorean , Thank you for the information.So, from STM32U5a9 side it supports DTR right?Its just from the Octal Flash end we need to set the command for DDR modewe are using ISSI Octal Flash chip BTW. RegardsSanath

Hi @adamfinch Below are the steps for performing an RWW (Read-While-Write) operation and the corresponding observations regarding the Bank Stat Register:We initiate the RWW write command for a specific bank.Without terminating the write task, we send...

Hi @Tesla DeLorean , Have tried giving exit paths also by giving CS HIGH still unable to read the BANK STAT.Dont know what we are missing. The Datasheet says First we need to send Command 0x85(READ VOLATILE REG) then the Address of BANK STAT(0x11) fo...

Hi @KDJEM.1 We are able to do the RWW operation by controlling the CS in software in multiplex mode .I am able to write to a bank and at the same time able to read the data from another bank. But there is one thing i need to read the BANKSTAT regist...
