MCU-PLUS-SDK-AM263X: UART BOOT mode using XDS110-USB

Hi Saman,

For UART boot mode, the BOOTMODE[1:4](SW3) = 1000.

The baudrate should be 115200

Hi Wang,

Yes that's correct and I have put MCU in UART Boot mode.

By the way, just to mention that I am using external XDS110-USB and have tried it with both AM263x-CC (Control card EVM) and my own designed PCB.

I do not receive character 'C' every one second on 'Serial terminal'.

Hi Wang,

Yes it is in UART boot mode.

I can see character 'C' is transmitted every one second on oscilloscope on UART0_TXD pin (A6) on Pin3 of U45 of the AM263x-CC, but I cannot see it in terminal.

As I am using external XDS110-USB. I have connected the debugger through J2 connector of TMDSHSECDOCK board as you can see below.

Please answer my questions below:

1. Is there any way to download my code into QSPI memory without connecting directly to USB connector of AM263X-CC? (Only with JTAG J2 Connection and external XDS110)
2. Is UART0 port (A7/A6 pins) dedicated for UART BOOT mode connection? Since I have connected UART2_TXD/RXD (B5/A3 pins) to UART of the auxiliary debugger connector (in my own designed board). Is there any way to use (B5/A3) pins for UART code download into QSPI memory?
3. Can I have the schematic of TMDSHSECDOCK docker board?

Hi Wang,

QJ Wang said:

Yes, you can use CCS to load files.

I could not find anything about loading code to QSPI via JTAG J2 connector which is located in the docker board.

QJ Wang said:

The schematics and layout files can be found in C2000Ware.

Would you please send me the link?

Hi Wang,

In my own designed board, B5/A3 pins are connected to debugger instead of A6/A7 UART0 pins. If I connect both UARTs together. (A6-->A3) and (A7-->B5). is it possible to load the QSPI using RBL?

I don't know if the logic in A3 and B5 affects the UART0 communication. Please try, and I'd like know if this idea works or not.

I connected A7-B5 and A6-A3, as you can see in the screen shot. Only first command (flash-writer) out of 3 commands in default_sbl_qspi.cfg is completed.

Do you have any idea why "--file=sbl_prebuilt/am263x-cc/sbl_qspi.release.tiimage --operation=flash --flash-offset=0x0" is not starting?

After first command the current consumption is increased meaning that the sbl is running but I don't know why the second command is not working fine.

How can I do this? (Downloading code into QSPI memory at the specific address, using only CCS and JTAG-J2 connector)
