JTAG emulator speeds ARM development
Ronetix has developed a high-speed low-cost JTAG emulator for ARM7 and ARM9 based microcontrollers.
This includes all DaVinci CPUs with an ARM926 core, like TMS320DM6446, TMS320DM6443 and TMS320DM6441.
Peedi can be used for high-speed GNU GDB debugging and Flash programming of all ARM7, ARM9, and XScale based MCUs, Freescale Nexus-enabled PowerPCs, ColdFire, Blackfin as well as the TI DaVinci DM644x.
The DM644x devices are based on TI's TMS320C644x DSP core and an ARM926 processor.
Because of its on-chip NAND Flash controller and the ability to boot using it, many hardware designers have decided to have a system with only a NAND Flash chip, without a NOR-Flash.
The built-in Flash programmer of Peedi supports programming of 8bit and 16bit NAND Flash devices connected to a DaVinci CPU via the JTAG interface.
Peedi offers various methods for ECC calculating, including bad block management and clean markers: hardware ECC using the DaVinci NAND Flash controller for UBL and JFFS2, standard software ECC for JFFS2, and ECC for YAFFS2.
The system also offers automatic generation of UBL descriptors.
The file image is relocated with one NAND Flash page and the skipped page is filled by Peedi.
Peedi supports several flash profiles which enable the programming of a complete Linux system at once.
