| Abstract: | Flash chip is used to save the firware which runs after system booting. Normally we use programmer to program the flash chip, which spends lots of time and reduce the life time of the flash. In this paper, we have introduced the architecture and debug flow of EJTAG, and analyzed various current methods, then introduce a new method for rapidly programming flash. This method has been successfully used in both FPGA and ASIC edition of EroSoc which based on MIPS CPU. |
