Flash Programming

The internal Flash of Oki MCUs are programmable through many different methods. Most of the debug and development tools noted above have built-in flash programming support for Oki ARM MCUs. The following vendors provide specialty products supporting production Flash programming. 

Company Product Description FSG manufactures mass production programmers. Some Oki ARM MCUs can be programmed by commercially available gang programmers from FSG.  Data I/O manufactures mass production programming tools. Oki MCUs can be programmed by vendors that have Data I/O gang programmers. Segger makes a series of in circuit JTAG Flash programming utilities. JFlash is one such low cost utility.  (YDC) YDC makes in circuit Flash programmers supporting Oki ARM MCUs
