Hi Ti Support Team,
I'm working on an ethernet based bootloader for microcontroller RM57L843.
I found the boot loader example in Ti forum mentioned in below link,
And I downloaded those exambles in below link,
I imported boot loader example program and included the boot and lwIP-1.4.1 files in CCS but those include files are not open in CCS.
Please tell me how to rectify it.
Thanks in advance.

Priyadharshini
Hi Priyadharshini,
Do the below steps and try
1. Right click on the corresponding folder and go to the properties window.
2. There you can see the folder path as doesn't exist
3. Now click on the edit option and reselect the folder path
4. Now you can see that exclamation mark(!) will get removed on the folder
5. Do the same thing for remaining folders as well.

Hi,Jagadish
For the below mentioned design files link is not loaded into the microcontroller.
git.ti.com/.../Hercules_Ethernet_Bootloader
Its shows program load error.
Please Supportr me.
Thanks & regards,

Hi Jagadish,
Thanks for your response.
After go through the above thread. The program was loaded into the microcontroller. But before connecting the ethernet cable the yellow and green LED in the Ethernet was turned on as below metioned picture.
And after connecting the ethernet cable.The cable was not detected in the ethernet switch.
Please support me.
Thanks & regards,

Hi Jagadish,
When I debug the code was hanging in,

Hi Ajith Kumar,
Apologies for the delay, i was stuck with some other issues from last two days.
I am attaching two projects here for your reference.
The first project is ethernet bootloader and the second project is LED blinky project which will blink two user LED's on launchpad for every one second.
I will explain what are the steps i followed to work with ethernet bootloader, here i performed static ip method instead of using DHCP
1. First configure proper static ip, subnet mask to the target board based your PC ipconfig
For example
My PC ipconfig is here
So, i configured my target PC static ip, subnet mask as follow
2. Now build the ethernet bootloader code and program it into the Target board. Once programming is successful connect a ethernet cable between your PC and target board.
3. Now reset the board then you should get below data in serial port
Note: Here serial configuration is, baud rate-19200, stop bits-2 and No parity
4. So static ip got assigned to the board, now open Tftpd32 tool to program the application through ethernet bootloader.
5. Do below configuration in Tftpd32 tool
At server interface, select your PC ip address. And select Tftp client menu, also give target ip at Host field and give port number as 69.
6. Once you did the proper configuration in Tftpd32 tool now select binary file path at local file field
This should be the binary file of the application you want to program through ethernet. In this case the binary file i provided in example application.
7. Once you select the binary file now you can click on "put" option to send binary file over ethernet.
8. Now you can see the target board programming steps through serial port as below
It will erase the necessary sectors in the flash to program the application and it program the flash in blocks wise.
9. Once programming the application, now make sure to connect GIO_A9 to the 3.3v
As i am using launchpad i shorted J1 connector 1st and 5th pin
10. Once you short GIO_A9 to the 3.3v then now reset the board to run application code by ethernet bootloader
And user LED's should blink on launchpad.
Here i used static IP right, if you want you can connect PC and target board to the router and assign dynamic IP's and can perform the step 3 onwards.
