Hi,
We having 8mminilpd4-evk, we trying to bring up ecspi2 memory MT25QL02GCBB8E12-0SIT.
We tried sf probe at u-boot.
But we were unable to see the device probing.
We can see the IO mux is configured for ecspi2.
Can you give us any lead on this one.
Thanks & Regards

this is critical issue, can anyone help us on this one.?
I hope you are doing well.
Yes, It is needed to check that the flash must first be probed with sf probe before any of the other subcommands can be used.
Please make sure you have given the correct sf probe command.
sf probe [[[<bus>:]<cs>] [<hz> [<mode>]]]
Please make sure the ECSPI initialization is appropriately done, If not then follow the procedure as mentioned below.
To initialize the block:
1. Clear the EN bit in ECSPI_CONREG to reset the block.
2. Enable the clocks for ECSPI within the CCM.
3. Configure the Control Register and then set the EN bit in the ECSPI_CONREG to put ECSPI out of reset.
4. Configure corresponding IOMUX for ECSPI external signals.
5. Configure registers of ECSPI properly according to the specifications of the external SPI device.
Please take a look at Section 10.1.5 ECSPI Memory Map/Register Definition of the RM to make sure the IOMUX pin setting is.

HI,
We were trying to bring up ecspi2 memory MT25QL02GCBB8E12-0SIT
We followed this post "https://community.nxp.com/t5/i-MX-Processors/ECSPI2-on-i-MX8M-Mini-EVK/m-p/904313" But we were unable to see the deviceat userspace or probing at boot time .
We tried to check at u-boot using $ sf probe , but we didn't seeing ecspi2 getting probe.
We tried enabling all the interfaces for ecspi2 u-boot menu config.
Can you please point out some leads on this one?
Thanks,

We were trying to flash ecspi2 using UUU .
Can you let us know what was the command used to flash ecspi2?
Thanks.
