24bit data bus width

[Anonymous]

is it possible to configure the data bus widt to 24 bits? I've checked the differences between 8, 16 and 32 bit, there only changes the 79th line in the last 8 bits (CY_U3P_PIB_GPIF_BUS_CONFIG).

   

I need 24 bit data width and SPI for my booting from SPI flash (firmware). If I look to the pin list in the datasheet , I can see that there is no intersection between data bus and SPI bus.

Yes. You can configure the GPIF II data bus to 24-bit.

   

Please do the following change in the GPIF II descriptors.

   

0x00000068,  /*  CY_U3P_PIB_GPIF_BUS_CONFIG

I checked about this internally and it looks like current SDK does not support the 24-bit data bus.

Is in SDK 1.2.1 or in future the possibility to change the data bus width to 24Bits? It is necessarry to have SPI boot, too, so I can't configure to 32Bits.

Understood.

   

Yes. We do have a plan to release the SDK which supports 24-bit as well. Currently testing is going on for 24-bit but the time line for release is not fixed yet.

        Hi, Is there any update on 24 bit GPIF II bus support. In particular, I need SPI available concurrently with 24 bit GPIF II. Thank you!
