AM2732: AM2732CD flash failed

zdd

Part Number: AM2732
Other Parts Discussed in Thread: UNIFLASH

I am currently developing with AM2732CD, and something strange is happening when I am flash and upgrading:
First of all, the chip is powered on in the uart mode. The serial assistant shows that the chip sends out two 'C' at a time. The cycle is about 4s.
Then I compiled helloworld, sbl_uart_uniflash, sbl_qspi in the sdk, and then downloaded it.

log如下：

PS C:\ti\mcu_plus_sdk_am273x_09_01_00_41\tools\boot> python uart_uniflash.py -p COM3 --cfg=.\sbl_prebuilt\am273x-evm\default_sbl_qspi.cfg

Parsing config file ...

Executing command 1 of 3 ...

Then it will brush sbl_uart_uniflash fail once, then success by try again, and then it wait for the sbl_qspi brush.
what the problem is?

Hello,

Are the images failing to load onto the device then? or do all 3 images fail to load once and then succeed?

as log prompt，just the first image sending 2% then failed ,and the second attempt was successful. the other two images never made it.

Hello,

I am observing the same behavior on an HSFS device, could you confirm if you are using HSFS? you can check the User Guide for information on how to distinguish it:

Full name of chip is AM2732CDRFHQZCEQ1,you say observing the same behavior on an HSFS device，Does that mean it's normal？

Hello,

I believe this is what it is expected from trying to use non compatible SBL images. From your device number I can see that it is indeed an HSFS device so that is the most likely explanation for the failure. I will bring in a software expert for help on this. Please allow them some time to comment.

Best,

Daniel

Hi,

Will you be able to try flashing and running from 9.2 SDK? Also request you to try with pre build images available at "tools/boot/sbl_prebuilt/am273x-evm"

Regards,

Ankur

Hi，

I am try flashing and running from 9.2 SDK with pre build images today，but it also failed，and the behavior is consistent.

Hi Zdd,

We have validated this from the 09.02.00 release and this is working for us. We are able to flash and boot the application on HS-FS device.

Was this working for you earlier on board you have or QSPI flashing is always failing?

Do you have any other AM273x EVM on which you can try out this scenario?

Regards,

Ankur

Hi Ankur:

I have no problem developing on AM2732AD at present. Now the same board is replaced with AM2732CD , which can't be flashed. Is your AM2732CD chip send two C onetime when entering uart mode.

Hi Zdd,

Receiving two C at stat in UART mode shouldn't be an issue.

To help us try to reproduce the issue can you please share below information

Are you using the AM273x EVM available on ti.com or using your customer build board?
If using customer build board, the setup for working and not working SOC is same?
Can you run the SOCID parser script for both working and not working SOC and share the details?
- Script is available at "tools/boot/socid_parser"
- Run command "python uart_boot_socid.py -d am273x -s <string on UART console in UART boot mode>". You can try pressing reset if you are not getting the string.

Regards,

Ankur
