LPC5536: Configure Flexcomm8 clock in Clocks Tool?

[danielholala]

Hello,

I'm prototyping on the LPC5536-EVK using MCUXpresso IDE 11.8.0 and SDK 2.14.0 (by SDK Builder).

I can configure Flexcomm8 with Pins Tool:

In Clocks Tool, however, there's no Flexcomm8.

There's a HSSPI clock, instead.

That's confusing.

Thanks @RaRo , that's an interesting workflow. Next time I'll start configuring using Peripherals Tool (instead of Pins Tool).

Hello @danielholala,

As you mentioned, in Clocks Tool the clock of the Flexcomm module 8 is named as HSSPI_clock instead of FXCOMx_clock like the others Flexcomm modules' clocks. This could be explained due to Flexcomm module 8 being configured for HS SPI usage as mentioned in the LPC553x Reference Manual.

For avoiding this confusion, you could use Peripherals Tool to configure both clock and pins. While you are configurating the driver, you could enable clocks, initialize the peripheral, and route pins related to it with the help of warnings in the Problems window.

In any case, we are letting the team in charge to know about this. Thanks for the feedback.

Best regards, Raul.
