T1024 QUICC Engine

raymondhaas — Tue, 21 Nov 2017 20:25:08 GMT

I am considering using the UART of UCC1 in the QUICC engine instead of the DUART controllers on the T1024. I need a UART that can automatically populate RX buffers with no processor (PowerPC core) intervention. This is a requirement of our end user.

My first question is where do I get a copy of the QUICC microcode? I have the Freescale SDK for the T1024RDB dev board. I do not see the QUICC microcode. However I do see the FMAN microcode.

My last question is whether the QUICC engine is recommended to be used. I tried to look for u-boot support and noticed there is little support. I also spoke to a representative of a real-time OS and was told that they don't recommend using the QUICC engine. At that time, I didn't ask why (I should of).

Thank you

Use SDK 1.9 for the T1024RDB board. This SDK supports UCC UART driver.

Press "Download" on the following page:

https://www.nxp.com/support/developer-resources/run-time-software/linux-software-and-development-tools/linux-sdk-for-qoriq-processors:SDKLINUX?tab=Design_Tools_Tab

Find previous revisions of the SDK.

Note: Documentation for current version of the SDK is available in source .iso file.

Have a great day,
