Thanks for your sharing.
I have tried this on raspberry pi 2. the led task can run well.
However, the network card seems not work. I can't ping this address through.

the network parameter in my LAN is:
network gateway: 192.168.1.1
Mask: 255.255.255.0

The default setting in the main.c is,
const unsigned char ucIPAddress[ 4 ] = {192, 168, 1, 42};
const unsigned char ucNetMask[ 4 ] = {255, 255, 255, 0};
const unsigned char ucGatewayAddress[ 4 ] = {192, 168, 1, 1};
which should match the setting in my LAN.
I can manually set the similar IP with my Ubuntu PC.

Looking forward your help. Thanks in advance.

I've been using this port on the Raspberry Pi 3B mostly with success. I found an interesting bug with the GPIO driver included in the port. In the SetGpio() function, there is an or equal (|=) used to update the GPSET and GPCLR registers. These registers are write only for the BCM2837 and BCM2836, causing some undefined behavior.

To reproduce this issue, probe several GPIO pins at once and toggle them on and off with varying duty cycles. This problem can be fixed by changing the |= to a = on lines 60 and 62. I will submit a pull request.

Build fails with multiple definitions of the symbol "loaded". Fix by changing Drivers/video.h

char loaded;

change to

extern char loaded;

I'm porting FreeRTOS to the Raspberry Pi Zero W, and I was probably going to use some of your code. What FOSS license would you like your contributed files to be under in my repository?

Thanks for your sharing.
As a beginner, I have some questions.
How to use the serial port to print?
Use TTL change USB or TTL change RS232?
Does it contain related drivers?
And I also can not ping the IP address.
So how to use the net export？
Looking forward your help.

Hi,
I try to understand the code, I see in the file gpio.c the line

volatile BCM2835_GPIO_REGS * const pRegs = (BCM2835_GPIO_REGS *) (0x3f200000);

How is the value 0x3f200000 decided ?

Thanks

First of all thanks for providing port for raspberry pi 2 model.

I'm facing problems while doing floating point arithmetic operations.
I can't add or subtract or multiply the float or double primitive type variables.
Can you please help me out and tell me what must be causing this?
