How to delete bootstrap code in 89lv51rd2
« on: April 01, 2009, 02:41:20 am »
I want to skip initial bootloder coding. I already updated my microcontroller with bootloder version 1.7 and choose ISP entry mode "user code if P0.0 high" ,but still i am getting  delay at time of power on reset .No difference in power on delay  between factory setting ISP entry mode and new setting. My crystall freq. is 2.0mHz.
Plz tell me how to delete bootloder.

Put it into a parallel programmer and erase all the flash in both blocks. I think that is possible.
