In-System Flash Programming 1,000x Faster
eBook | IJTAG
New faster methods for the in-system programming of onboard flash as well as I2C and SPI memory are explained in a new eBook published by ASSET InterTech.
In-system programming has many advantages over standalone programming stations. Advanced programming methods based on the IEEE 1687 Internal JTAG (IJTAG) standard and embedded programming engines in an onboard FPGA can accelerate programming speeds by a factor of 1,000, shortening the process from tens of minutes to a second or less.
“In many cases, the contents of FPGA-connected flash is not available when prototypes of a board design are produced. And production engineers often don’t know what version of the firmware to load until a customer orders a system,” said Kent Zetterberg, author of the eBook and an ASSET product manager. “In cases like this, in-system programming is the best solution. Faster programming speeds make it even more effective.”
