Part Number: C2000WARE
In many example projects there is this statement:
SysCtl_setLowSpeedClock(SYSCTL_LSPCLK_PRESCALE_4);
However in the projects below the definition used is SYSCTL_LSPCLK_PRESCALE_14
I have had to rebuild a project after a rename snafu and some code that got pulled in used the ..._14 value. So I spent a good amount chasing this down because our setup with the F28386S needs the lower value.
Using the search tool "Everything" I found these files in C:\ti\c2000\C2000Ware_4_01_00_00 use SYSCTL_LSPCLK_PRESCALE_14. There are also examples in the same space for the same devices that use the other value. So beware if your UART quits working because many examples do not use the default of SYSCTL_LSPCLK_PRESCALE_4.
