AM2634: Recover without UART connection

Hi Mykola,

The only other option is to use the sbl_jtag_uniflash to flash the sbl_qspi and applImage into the QSPI flash, but it requires the JTAG and the gel file to initialize the SOC. The project is at C:\ti\mcu_plus_sdk_am263x_08_06_00_34\examples\drivers\boot\sbl_jtag_uniflash. Please refer to the AM263x MCU+ SDK: CCS Launch, Load and Run (ti.com) "Load and run example binaries" section for how to initialize SOC using gel file.

Best regards,

Ming

Hello Ming,

Thanks for your support

After erasing the flash completely on Launchpad, I tried to use CCS Debugger and Lauterbach debugger connected to JTAG. Did not succeed in establishing the connection in both cases.
- Is SBL needed to be present at 0x00 to be able to establish JTAG connection?
- If SBL is corrupt or erased, is there a way to establish JTAG connection using CCS debugger or Lauterbach debugger?

Hi Mykola,

Have you tried the following?

AM263x MCU+ SDK: CCS Launch, Load and Run (ti.com) "Load and run example binaries" section for how to initialize SOC using gel file

If yes, then there is no other way to halt the  R5F_0_0

Hi Ming,

thanks for your  response 

Well It seems after power of board successfully initialize R5 to be able to connect but then

when I am trying to start binary I have follow error occurred. 

Hi Mykola,

It looks like the M4 (HSM) was not in the correct state. 

Can you try to use the Scripts --> AM263x Device Configuration --> R5_ROM_eclipse, before you load the binary file?

Best regards,

Ming

Hi Ming, 

Yes I am trying to perform  R5_ROM_eclipse before load bin file but unfortunately it still crashed during booting up

[Cortex_R5_0] ASSERT: 0.3s: soc/am263x/soc_rcm.c:SOC_rcmGetCoreFout:1521: FOut != 0 failed !!!

Any clue how to solve this problem would be appreciated
