125Re: [OKI-ARM-mcus] Having trouble with flash_uty_38400_5K.hex
- Nov 4, 2005Hi James,
I think the problem is with the oscillator
frequency. ML67Q500x series has a built-in PLL , which
for an external oscillator can operate at 4x/8x
speeds depending on CLKMODE selections (These are
hardware connections). So if you have a 7.5 Mhz
external osc. your cpu can operate at 7.5 X 8 = 60
Mhz. Form your query it seems that u are a pretty
older method for flash programing . Thankfully Oki
has put up a useful IAP utility called OKI ISPF at its
website which is much more handy.
