Hi Duong,

Looks like you have set the boot mode to QSPI which is not the boot mode for flashing the initial binary (SBL_NULL) into the on board QSPI flash. Please refer to the following URL: https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/08_01_00_36/exports/docs/api_guide_am243x/EVM_SETUP_PAGE.html#EVM_FLASH_SOC_INIT

You will need to download and install the MCU+ SDK 08.01.00.36 from: https://www.ti.com/tool/download/MCU-PLUS-SDK-AM243X

Best regards,

Hello Mr Ming Wei,

Today i check the guide that link you sent to me.

Almost is done but i can not flash sw to LP-AM243x board.

Download fail and have the same result with both UART mode and QSPI mode.

What is the mode to flash sw to LP-AM243z. As i know it is QSPI mode, right?

Can you help me for some advise.

Here are my process:

1. Cable Connections: ok

2. Setup UART Terminal: ok

3. Flash SOC Initialization Binary: ok

-->But flash SW to LP-AM243x still fail as text below

"CS_DAP_0: Error connecting to the target: (Error -1170 @ 0x0) Unable to access the DAP. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 9.6.0.00172)"

"Unable to connect to the target"

-->Fail the same with both  boot mode config: UART and OSPI

QSPI Mode                                                                                                                            UART Mode 

Hi Duong,

Looks like you have flashed the initial SBL_NULL to the flash successfully.

After that, switch to OSPI boot mode, then connect UART. You should see the following display on UART output:

Once you see the correct UART display, then you can launch the AM243xXDS110.ccxml and connect to the R5_0_0 core. The paused address should be either 0x44 or 0x00, then you are ready to load your application code (like HelloWorld).

Bestregards,

Hello Mr Ming Wei,

How can i setup paused addred to 0x44 or 0x00.

Pleade guide me, it is the first time i work with CCS and TI chip 

thanks,

Hi Duong,

Refer to AM243x MCU+ SDK: CCS Launch, Load and Run (ti.com) for how to get to 0x44 or 0x00 for R5_0_0 in CCS.

Best regards,

Ming

Hello Mr Ming Wei,

Thank you so much for this time.

It very helpful with me, i can flash for chip.

Today i check the ethernet sample with the link on Resource Explorer:

lwip:

      - enet_lwip_CPSW

      - enet_lwip_ICSSG

They run well but i saw that the IP is always are: 0.0.0.0

Here is the guide line from e2e.ti.com: software-dl.ti.com/.../EXAMPLES_LWIP_ENET.html

• If you see a valid, non-zero MAC address but IP address is 0.0.0.0 then
  • Make sure you see link_callback==UP message, if not check the ethernet cable
  • Check the local network and check if the DHCP server is indeed running as expected
  • When using a home broadband/wifi router, its possible to check the clients connected to the DHCP server via a web browser. Check your router user manual for more details.

-> You can see above image: "link_callback==UP"

-> DHCP server  is OK via check gate way by web browser: http://192.168.1.1/

-> LAN Cable is OK 

->I also double check the IP range and LAN connection. every thing is ok.

Can you explain for me: why ip always 0.0.0.0 instead 192.x.x.x

I am sorry because i just start with program firmware for TI IC.

thanks and best regards,
