Hello TI team,
We are trying to boot our board using the below pin boot mode configuration:
SW3 : 11011100
SW4 : 00000000
but we are not getting the entry string which we are expected to get before loading the SBL file on the microprocessor.
Is the primary Bootloader already flashed on the processor or will we need to flash that ?
Please tell me the steps to get the entry script after booting in UART mode.
Best Regards,
Vaibhav V Agavile.
Hello Vaibhav,
To confirm, are you using a TI EVM?
You can find basic EVM setup information about flashing an SBL here:
https://software-dl.ti.com/mcu-plus-sdk/esd/AM62X/10_00_00_14/exports/docs/api_guide_am62x/EVM_SETUP_PAGE.html
and information about SBL options in the MCU+ SDK here:

Hello Nick,
We are not using TI EVM, but we are using our Customized board and we use the TI EVM schematic as reference.
Now, my question is regarding ROM Bootloader(RBL) is Read Only Memory programmed into the chip during production by TI before being shipped to TCS, please confirm?
We are using UART boot mode on our custom board, but we are not getting any string on UART as mentioned in your procedure.
Kindly, provide the debug step to solve this issue.
We are using this SOC with part no. : AM6201ASGFHIAMCRQ1.

Hello Vaibahav,
You can find some basic information about the ROM bootloader in the AM62x Technical Reference Manual (TRM), chapter "Initialization".
I am reassigning your thread to another team member for additional comment.

Yes, the ROM is stored in the device an executed after power up.
if SW3[1:8] = 11011100, then you should be getting the "CCC" in the terminal window. Please check Section 1 here: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1358039/faq-board-bring-up-tips-for-sitara-devices-am64x-am243x-am62x-am62ax-am62px
for debugging tips. If you are still stuck, please post here
