大家好:我有一块富昌的MC9S08QG8的开发办。评估板上的BDM是使用MC908JB16制作的。问题是:每次通过BDM把MC9S08QG8的程序擦除后,如果再连接编写程序时总是很难烧写程序,出现的错位为:File does not exist: startup.cmd File does not exist: preload.cmd File does not exist: postload.cmd。同时调试连接时非常困难,很难连接!
我也遇到了,确实不好用,你参考下富昌提供的资料《FMBB_user_manual.pdf》,
9. Forcing the FMBB into BDM Mode:
With the USB cable connected to the FMBB, move the 3.3V_SEL shunt from position 1-2 to position 2-3, as in Figure 6.3.1.1-9.
Install a shunt at BDC_CON pins 1-2, as in Figure 6.3.1.1-9.
After approximately 5 seconds, move the 3.3V_SEL shunt to position 1-2.
Remove the shunt from BDC_CON pins 1-2.
The MC9S08QG8 is awaiting the execution of the ‘SET GDI’ command.

在富昌的评估板上,百试白灵,其他的板子上有时候不行。
还有个hcs08unsecure.cmd 不知道怎么用?请指教。作者: tao0599 时间: 2007-1-20 13:42
you can download the update pack here.
https://www.freescale.com/lgfiles/updates/CWHC08/HC08V5_1_OSBDM_SP.exe
after installing it,you must reinstall your OSBDM driver for windows.otherwise the OSBDM will be wrong,when you use it again.
