MCU-PLUS-SDK-AM243X: Flashing of default_sbl_null.cfg fails on AM243X-LP with MCU+ SDK 09.00.00

Part Number: MCU-PLUS-SDK-AM243X
Other Parts Discussed in Thread: UNIFLASH

Hello community,

I tried to flash default_sbl_null.cfg on my AM243X-LP with uart_uniflash.py included in the latest MCU+ SDK 09.00.00 release as described in Flash SOC Initialization Binary, but it always failed at step 2 of the config file. I retried the same steps with the MCU+ SDK 08.06.00.45 release and it worked just fine. After some investigation I found out, that different images will be flashed in both releases:

09.00.00: sbl_null.release.hs_fs.tiimage

08.06.00.45 : sbl_null.release.tiimage (missing in 09.00.00).

Did I miss something here or is the wrong image used in 09.00.00?

Best regards

Hi Philipp Finke,

Can you check which device type are you using ?

Use this FAQ for the same - https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1119575/faq-mcu-plus-sdk-am243x-how-to-debug-sbl_qspi-for-am263-and-am273-or-sbl_ospi-for-am243-or-an-application-which-is-booted-via-ospi-qspi-boot

Hi Philipp,

I have added the correct link here for the FAQ - https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1170785/faq-mcu-plus-sdk-am243x-how-to-identify-if-the-device-is-gp-device-or-hs-device

Hey Aakash,

seems like I have a GP device. Now it makes sense that the HSFS image didn't work. Also it's strange that the script reported that I have an AM64x device although it's definitely an AM243x on the PCB.

I would recommend to readd the SBL NULL image to the MCU SDK. Others will have this kind of issue, too.

Hi Philipp Finke,

Let me take this as a valid requirement to keep SBL_NULL for GP device as part of MCU_PLUS_SDK with SBL_UART_UNIFLASH but I would still suggest you to migrate to latest evm version which contains the RTM part of AM243x i.e. PG2.0
