Detection of QSPI in custom board designed using RT-1176

[ManikantaRobbi]

Hi,

we had designed custom board with QSPI flash connected to FLEXSPI-1 interface.

I had connected with your team members regarding flashing issues, they advised to use LINK TO RAM Application process and flash flexspi_nor_polling_transfer.c  to detect and get the device id=0x9d.

But I'm getting 0xff, so 1.Checked the clock it is working fine.2.Probed MISO pin(NO-2) by removing resistor R73 which is connecting to RT1176 then I'm able to get 0x9d in scope but when I replaced the resistor the same issue with result 0xff. Kindly help me top resolve the issue.

Thanks & Regards

Hi @ManikantaRobbi ,

As you mentioned ".Probed MISO pin(NO-2) by removing resistor R73 which is connecting to RT1176 then I'm able to get 0x9d in scope" , was the MISO pin disconnected with RT1176 in that case? For the resistor such as R72 and R73 between QSPI flash and RT1176, are they placed close to the QSPI flash pins? Please kindly clarify.

Have a great day,
Kan

Thanks @Kan_Li , We sorted the issue, actually the problems arises due to HYPERFLASH and HYPER RAM module sharing common DATA pins as you can see below attached image so we tried to remove  HYPERFLASH chip first but failed to get 0x9d.And later we removed HYPER RAM also which gives successful detection and program ERASE/FLASH & VERIFIY. As of now QSPI is working fine, but our requirement is HYPER FLASH  not Flashing into QSPI. So we want driver and steps to to use S26HS512TGABHI000.

Thanks & regards

Hi @ManikantaRobbi ,

You may refer to https://github.com/JayHeng/RT-UFL/blob/master/README-en.md for details regarding the flash driver development.

Hope that helps,

Have a great day,
