Confirming BSPs for various chips and tower system

[michaelschwager]

Hi, I find I'm confused about the BSPs that are generated from the BSP cloning tool.

I'm using various flavors of K60, MQX 4.1.1.

I vaguely recall there was something about silicon versions that made it non-obvious which BSP to use for a given tower system, and this had a significant effect on the code used for the clock init code, ie if you used the obvious one it didn't work, so you had to use a non-obvious one.

I've also noticed that the CPU target in a BSP is different from what the chip label says, which I think is part of the above recollection.

Can someone please confirm the following BSPs and CPU targets are correct for the following configurations?

I'm mostly concerned that I'm using the right BSP for my custom boards.

PCB/Hardware	CPU name on chip	Clone tool board name	config.h CPU identification	Cloned CPU target for BSP	Cloned CPU target for examples
TWR-K60N512	PK60N512VMD100	twrk60n512	PSP_CPU_MK60DN512Z	Cortex-M4	MK60DN512Zxxx10
TWR-K60F120M	MK60FN1M0VLQ12	twrk60f120m	PSP_CPU_MK60DF120M	Cortex-M4	MK60FN1M0xxx12
Custom V1	MK60DN512ZCAB10R	twrk60n512 -- ???	PSP_CPU_MK60DN512Z	MK60DN512Zxxx10	MK60DN512Zxxx10
Custom V2	MK60DN512LVQ10	twrk60d100m -- ???	PSP_CPU_MK60D100M	MK60DN512xxx10	MK60DN512xxx10

Why is the Z target used for PK60N512VMD100 tower chip?  I understand Z is initial silicon, but this is not printed on the chip on the tower PCB.

Why does the BSP merely target the core (Cortex-M4), but the examples target the specific CPU (MK60DN512Zxxx10) ?

Short version posted here:

Which BSP to use?

Thanks

In fact Z isn’t "real" initial silicon. TWR-K60N512 is assembled by first silicon (part number without Z and D/F, maskset 0M33Z). Z was later added to part number for distinguish between Rev 1.x and Rev 2.x Kinetis 100MHz chips during renaming. New Kinetis 100MHz chips names contains “D” or “F” in part number for specify core type:

D means ARM Cortex-M4+DSP

F means ARM Cortex-M4+DSP+FPU

So, Z means initial silicon only for already renamed Kinetis MCUs (with D/F in part number).

I would like to recommend our application note AN4445 Kinetis 100 MHz Rev 1.x to Rev 2.x Migration Guide for more details:

Simplest exact identification is trough maskset:

xM33Z and xN30D refers to twrk60n512

xN22D refers to twrk60d100m

Have a great day,

Thanks again. Yes I noticed the chip on the tower didn't confirm to the later naming convention so that's why I was confused. The mask set number matches.
