• Resurrector PXA3XX contains only NAND DCC Loader, thus it is to be used only for operations on DCC Read/Write page in the JTAG Manager.

Embedded DCC Loader is designed to work inside of MCU's internal RAM memory, thus it is not sensitive to external SDRAM configuration or availability or its physical state.

21.03.2011 - RIFF Box Firmware v1.21

Firmware 1.21
---------------------------

• Added RX-polling feature (debugger-to-target) for PXA3XX DCC transfers.

RIFF BOX firmware is able now to wait (if resurrector DLL will request so) for PXA3XX target to be ready to accept
next packet over DCC: this feature slows down a little the JTAG-to-Target DCC
transfers but guaranties no packets loss for slow clocked targets;
