Tool/software:
I have followed the bootloading over etherent sdk in msp432e401y . I got the output in the serial terminal as "Device ready to accept magic packets on UDP port 9" , now how do i flash my required code(magic packet) over the ethernet . I used BSL scripter to achieve the above " Device is ready ...".
Also is there any complete guide to flash a custom code over the ethernet apart from the BSL scripter SDK.
First of all, did you run the examples by running the three scripts as follows.
I got the output in the serial terminal as "Device ready to accept magic packets on UDP port 9" ,
If you have come this far then the boot_emac_flash_magicpacket_MSP_EXP432E401Y.txt example firmware has been loaded by running script 2. The boot_emac_flash_magicpacket_MSP_EXP432E401Y is already an example firmware. You can reference this example to create your firmware to be loaded by the custom loader.
now how do i flash my required code(magic packet) over the ethernet
If you look at the example firmware where you can find the full source code at C:\ti\simplelink_msp432e4_sdk_4_20_00_12\examples\nortos\MSP_EXP432E401Y\boot_loader\boot_emac_flash_app_magicpacket_update, it waits for a magic packet. By running script 3, the PC will send the magic packet to the MCU and once received, the firmware will jump to the bootloader again to program another firmware. In script 3, it will download a blinky example through the Ethernet port. You can use any application you want.
I am getting invalid TFTP error once i run script 1 of this example . Please give the step by step by instruction on how to do this, starting with an MSP connected to a Router with DHCP alone. I am unsure on how to get a BLANK MSP as mentioned in this guide from ti.
The steps i used to reach the previous state where bootloader was configured
1) FLash serial_emac_flash example
2) Use manual erase option in Uniflash
3) Reset the MSP
4) Run this script
LOG
MODE Ethernet E4xx MAC=70:FF:76:1C:E5:73 IPClient=192.168.0.2 IPServer=192.168.0.3
RX_DATA_BLOCK_32 boot_serial_emac_flash_MSP_EXP432E401Y_nortos_ccs.txt
in BSL scripter
5)Reset the MSP
6) Run this script
LOG
MODE Ethernet E4xx MAC=70:FF:76:1C:E5:73 IPClient=192.168.0.100 IPServer=192.168.0.3
RX_DATA_BLOCK_32 boot_emac_flash_app_magicpacket_update_MSP_EXP432E401Y_nortos_ccs.txt
I have both my laptop and MSP with the router.
Hi,
I cannot reproduce your problem. I run the examples on the MSP432E LaunchPad. See below where I run both script 1 and script 2. Before I run the script, I make sure the flash is fully erased. I also use the Wireshark to view the traffic. After the flash is first erased, I wait until I see a BOOTP request shown on Wireshark before I execute the script 1. After the custom bootloader is programmed to flash, I reset the board and again wait for a BOOTP request before execute Script 2.
Script 1 log:
Script 2 log:
Wireshark showing BOOTP, ARP and TFTP.
The above is the output when we used script 3 to flash a program "linked" to 0x4000 , we are not really sure what you meant by linked to 0x4000 but what we have done is modify the .txt file and increment the @location by 4000 so initally @0000 and @0040 are replaced with @4000 and @4040
Look at the .cmd for boot_emac_flash_app_magicpacket_update example where the firmware will start at 0x4000 because the bootloader config file expects it to start at this address. As said, you can change it. You need to make sure you change the bl_config.h file for the flash bootloader and the .cmd file for the application.
#define APP_BASE 0x00004000
MEMORY
{
FLASH (RX) : origin = APP_BASE, length = 0x000FC000
SRAM (RWX) : origin = 0x20000000, length = 0x00040000
}
Yes, it is the release.cfg file. There should be a dependency project in your workspace called tirtos_builds_MSP_EXP432E401Y_release_ccs in your worksapce on which all other TI-RTOS examples depend on.
I have added it to the release.cfg file , now if I change the origin of flash in msp432e401y.cmd i still get this error
