In mapClocks() is written to reserved bits of CLK

systemREG2->CLK2CNTL = (systemREG2->CLK2CNTL & 0xFFFFF0F0U)
| (uint32)((uint32)1U << 8U)
| (uint32)((uint32)1U << 0U);

Can you please check this?

Hello Kevin,

it's the TMS570LS3137 with Halcogen 4.05.01 Code.

Best regards
Thomas

Thomas,
You are correct that on TMS570LS3137 that the bit field CLK2CNTRL.11:8 is unused; therefore the write to that bit field has no impact.
Other devices have a bit field in this location.
