Flash Erase default value Awaiting Agent

Hi,
i'm erasing the Code flash by using the Trace32 by using below command.
¤tTime1=os.timer()

do &commonScriptsPath/operations/reset

print "&consoleMessage"

do initFlashDriver

FLASH.ReProgram &startAddress--&endAddress /Erase
FLASH.ReProgram OFF

do &commonScriptsPath/operations/reset

¤tTime2=os.timer()

&timeDelay=¤tTime2-¤tTime1
print "done: erase time = &timeDelay ms"


after erase code flash is not filled with default value "FFFFF" but i can see "??????". why it's not filled with FFFF?

Hello, The erasing state of memory is related to the Flash memory itself. After erasing, some Flash memory is set to '1', others to '0', and in some cases, like yours, the erasing data appears as undefined data. This behavior can be considered normal as long as you can flash your target without problems.

Hello,

In this case, please open a new ticket: "https://support.lauterbach.com/new-ticket".

After flashing, generate a system information report about your TRACE32 configuration for both cases by selecting the TRACE32 menu 'Help' > 'Support' > 'System Information...', click 'Save to File', and send the resulting text file as an attachment to your email.

Additionally, please provide us with the script you are working with or the list of commands you use, along with a short description.

Our support team will take over from there.

Thank you.
