LP-AM243: QSPI Flash write errors

Motoyasu Hattori

Part Number: LP-AM243
Other Parts Discussed in Thread: UNIFLASH,

Hi,
My customer is facing the Flash write error on all example and demos with QSPI Flash. So they tried returning initialized status, but the following errors are occurred.
The following is log of execution, "AM243x MCU+ SDK 11.01.00 > Getting Started > EVM Setup > Flash SOC Initialization Binary".

Hi,

Could you let me know if the customer is using a custom board or an EVM?

Best Regards,

Meet.

Meet-san,

This is LP-AM243 EVM.

Hattori-San,

Can you ask them to try the SoC initialization using CCS scripting and see if that works: AM243x MCU+ SDK: EVM Setup

If this works, they can try to run the OSPI Flash diagnostic example and share the results: AM243x MCU+ SDK: OSPI Flash Diagnostic

Best Regards,

Meet.

My customer did the above scripting, however, the following error is occurred. Could you please advise us how to fix it?

Hi Hattori-San,

This seems to be an issue related to Flash read/write itself, I am assigning this thread to our OSPI expert, please wait for their response.

Best Regards,

Meet.

Hi,

Since the DUT is not a custom one, and the default TI EVM that is AM243-LP, hence the default examples should work just fine and you should not run into any issue.

I am also assuming since the EVM is TI EVM, therefore the flash on it is S25HL512T.

For a good measure, can you please check if the SoC type is HS FS or GP.

The quickest way you can do so is by referring the following FAQ: e2e.ti.com/.../faq-am6xx-how-to-check-if-device-type-is-hs-se-hs-fs-or-gp

Let me know the results.

Kind Regards,

Vaibhav

Vaibhav-san,

They checked the following. Result is as HSFS device.

Can you please confirm if the flash is as mentioned in the highlighted response?

Looking forward to your response.

Flash error is occurred on EVM's Software. That is why we are asking. We want to know how to resolve this error.

Hi,

Given its a TI EVM and the SDK flashing fails, this is unexpected. It might be that the customer had made some changes earlier in the SDK, which might be causing this issue. This might be one of the reasons for sure.
Could you try the following:

Reinstall the MCU PLUS SDK and flash again, if it does not flashes still, then proceed to the next step.
Please refer: [FAQ] AM62X/AM64X : [FAQ] Debugging SBL boot in RTOS SDK

Vaibhav
