some troubles with SiLabs c8051f041

Mihail Minakov

Hi!
I have some troubles with SiLabs c8051f041. I try to start very simple program - flashing one led on gpio. I use Keil CA51 Compiler Kit. Program succesfully compilates without errors. Then I program my chip c8051f041 with BeeProg+ programmer. When programming is succesfully finished, I try to power ON my chip. And nothing happened... I don't understand what I am doing wrong?

    Thanks for quik answer.
    I configure the XBR0=0 - port1 pins is digital out puts and P0MDOUT=0b10000000 - P0.7 is push-pull output. Anod of LED is connected to P0.7 through resistor 1k to GND
    I connect the oscilloscope to LED pin and see the half of Vdd on this pin. Then I connect the oscilloscope to P1.7 (I write XBR1=0b10000000 SYSCLK routed to Port pin.) and I see the half of Vdd on this pin. I must see SYSCLK, but I see nothing.
