Processor Expert Flexbus port size setting

[jimbrady]

When I set Processor expert Flexbus (external bus) port size to 32 bits, It is actually setting port size to 8 bits.  I confirmed by looking at FB_CSCRn register setting in "generated code".  Has anyone else seen this issue ?  I noticed this because I am doing 32 bit wide read/write to external bus and the CPU is generating 4 bus transactions instead of 1.

Processor:  Kinetis K70

CodeWarrior 10.6

Windows 7 machine

Thanks,

Jim

Hello Jim,

In the generate code , it seems have a bug , from the Reference Manual , when set the 32-bit port size,

the PS is "00", while the generate code is "01"(8 - bit port size):

The workaround is change the "01" to "00" by hand , and in order to prevent the code change to "01 ," please disable the generate code of CPU at here:

Hope it helps

Have a great day,
Alice Yang
