How do I disable the T1042 Serdes PLLs in Codewarrior?
We do not have any hardware that uses the Serdes on our custom board and need to disable it as the board is stuck in a reset loop if this isn't set. We can set it with the USB Tap, but that obviously isn't product intent.
The T104x manual says in Section 31.1.1.3 Disabling Unused SerDes Modules:
SerDes is disabled as follows:
• SRDS_PLL_PD_S1 = 11 (both PLLs configured as powered down)
• SRDS_PLL_REF_CLK_SEL_S1 = 00
• SRDS_PRTCL_S1 = 0xFF
(no other values are permitted when both PLLs are powered down)
How do I do this in the RCW so that it happens on CPU reset? The CodeWarrior QCVS has GUI selections for these fields, but I can't specify 0xFF for the SRDS_PRTCL_S1 Field, I can only select from the GUI options.
Thanks,

To be able to use any custom values for RCW fields in PBL tool you should select the Advanced tab, then Ignore Constrains and non-Critical Errors.
In this way, when you will select the SRDS_PRTCL_S1 field, you'll see the Custom Bitfiled Value option.
Enter the value, select the Custom Bitfiled Value and Apply.
