What IDE is recommended for programming the LS1020A/LS1021A/LS1022A?

The LS1 series is optimized for CodeWarrior, whose latest version, for ARMv7 can be found at http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=CW-LS-ARM7&fsrch=1.


What is the LS102xA product family's enablement schedule up to 2016?

Can one CodeWarrior license cover both LS102x QDS and TWR?

The full CW product can be used with either the TWR or QDS board through the CW-TAP probe.


Does CodeWarrior for LS1 support flash (NOR/NAND) programming?

Yes, CodeWarrior supports both NOR and NAND programming for QDS and TWR.


Over what power range is LS102x designed for?

LS102x is designed for operation under 3W.  Its ability to yield over 5000 Coremarks at a frequency of up to 1GHz separates the LS102x family from competitors in delivering improved performance without increased power consumption.


How fast does the LS102x family run?

The LS102x family can run between 600 MHz and and 1 GHz.


What endianness does LS102x follow?

The LS1 is based on the ARMv7 architecture, which is natively little-endian.  However, ARMv7 supports big-endian using the CPC15 register.  More significantly, many LS1 peripherals, like Ethernet and integrated flash controller (IFC), follow big-endian.  Therefore, LS1 is really a mixed-endian system and one must be mindful of a peripheral's endianness when programming the LS1.
