5 Known issues
5.1 Compact Flash card Driver
- Some Compact Flash cards does not work correctly with TWR-MEM and MQX CF Card driver.
An issue in the TWR-MEM CPLD code REV A causes incorrect communication with some types
of cards (e.g. Kingston). A fixed CPLD firmware is available in
of cards (e.g. Kingston). A fixed CPLD firmware is available in

folder
.
The firmware
can be loaded to the TWR-MEM CPLD using Altera Quartus II design tool and BLASTER
connection cable.
connection cable.
5.2 Ram target
- Example projects contain different build configurations for code execution from Flash or RAM
memory. The RAM-based execution may be faster to debug but not all examples fit into RAM and
may fail to link.
may fail to link.
5.3 Flashing issues in CW 10.2
- K21D50M has issues flashing by J-Link in CW 10.2
6 Other notes
- For KEIL ARM Compiler, the libraries are pre-compiled for “Release” target only, “Debug” target
need to be compiled before first use.
