µTasker general / Different UARTs for send and recieve

« on: April 27, 2008, 06:48:06 PM »

Hey Mark,
I've checked through the documentation but haven't been able to find the answer to whether or not there is an easy way to use a different UART channel for sending and receiving.

With the default implementation, it looks like both use the SerialPortID which gets set to DEMO_UART in fnSetNewSerialMode.

It looks as if I will have to create a new SerialPortID using a different channel, that way I will have one for input and one for output.

Then I will have to replace all references to SerialPortID that are used in reads with SerialPortIDIn and all that are used in outs with SerialPortIDOut.

Is there an easier way to do this?

Thanks,
Jesse

NXP^TM M522XX, KINETIS and i.MX RT / Not getting LINK LED

« on: April 24, 2008, 10:37:50 PM »

Hey Mark,
I want to thank you for all the help you have provided so far.  The progress we've made would not have been possible without you.

We have everything functioning when our M52235evb is connected directly to a laptop using a crossover cable.

However, we need to put the device on our academic network.  I have talked with ITS and they assign an IP address to a MAC address.

To ensure that we do not conflict with any other MAC addresses on campus, we used an address that started with FF:.....

I've updated the IP configuration variables in application.c including the MAC, IP, Net Mask, Gateway and DNS servers to match with the network I will be plugging into.

I verified that USE_DHCP and USE_UDP are defined in config.h.  I also tried running with the ACTIVE_DHCP commented out and uncommented with no change in results.

However, I do not get a LINK light when I plug the M52235evb into our network and reset the board.

The settings look fine in the "Configure LAN interface" menu after doing a 'show_config':

IP address = 129.CORRECT
MAC address = ff-CORRECT
Subnet mask = 255.255.255.0
Default gateway = 129.CORRECT
LAN speed AUTO
DHCP_SERVER - enabled

* Correct used to replace some of the digits but represent that the values are as expected.

One thing I noticed is that the ARP table is empty.  Should it at least contain the DHCP server?

arp -a
ARP Table contents:
End

I've tried disabling DHCP_SERVER and the same results were seen.

I do not really think I can run WireShark on the network.

This may be a problem with the registration from ITS but I just wanted to see if there is anything you can think could be the problem.

Thank you.
