Tool/software:

Reference:

Host TDA4VM https://www.ti.com/tool/SK-TDA4VM

Can TI provide example source code to Configure the TDA4VM Octa-Interface for xSPI 8d-8d-8d accesses.

Would be great if the source code provides necessary steps to enable DQS (associate tuning steps) and setting dummy cycle count.

Appreciate TI's review and feedback.

Target OS is QNX.

Does TI have drivers for the Macronix MX25UM51245G?

Hello Ken,

Target OS is QNX.

First, the OSPI/xSPI driver is part of the QNX BSP. QNX owns and supports all QNX BSPs for TI devices/platforms, including TDA4VM/SK-TDA4VM.

So we suggest you contact QNX for support on this.

Thanks.

We suggest you look into the TI Linux SDK to see if the OSPI driver supports it.

The Linux Kernel is online here.

Check if the specific flash part is supported here -> https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/drivers/mtd/spi-nor/macronix.c?h=ti-rt-linux-6.6.y .

Thanks.
