Hi, I am using STM32L4S9 with macronix Octa flash(MX25LM51245GXDI00) and I am trying to erase octa flash getting the error "Mass erase operation failed." is their any feedback from ST team We are using STM32CubeProgrammer 2.5.0 Thanks, Ashok

Isn't that a very old version of the software?

You mention a chip, is this on a custom board or one from ST?

Do you have a board appropriate external loader?​

Hello @ab.7​ ,

I advise you to try with latest release of STM32CubeProgrammer v2.9.0.

Then, please keep us informed about your update.

I already used STM32CubeProgrammer V 2.9.0 and tested again. This did not change anything.

log for the cube programmer

1)Downloaded new version V.2.9.0 still facing the same issue

2 )Custom board

3) Yes

Attach a full log at Verbose 3 level.

Currently looks to have hit a 5 minute timeout​.

I​n your own experiments/testing of the BSP, how long does the full chip erase on the OCTOSPI usually take?

Attached the complete log file.

Downloaded new version V.2.9.0 still facing the same issue

Can someone perhaps look at why the tool times out after 5 minutes for a memory that has a maximum mass erase time of 10.5 minutes? Typical is >3 min.

Perhaps need a better method for communicating these times, and making sure the loader is still alive/functioning. Perhaps a progress call-back, or a TestReady type call-in.

>>I​n your own experiments/testing of the BSP, how long does the full chip erase on the OCTOSPI usually take?

@ab.7​ ​ Any information on this? Testing your BSP (BOARD SUPPORT PACKAGE) in a normal application, outside of the loader to establish the performance and function of the chip on your board. This would be a normal part of custom board bring-up and validation tasks.

for full chip erase it's taking around 3 minutes.
