IDE cannot find MEM-AP (LPCXpresso54608)

[hosseinragheb]

My LPCXpresso54608 board seems to have got a problem with power as the MCUXpresso IDE can no longer debug/flash code using the board, although it finds the probe. Below is what I get from the debugger. Also using LPCScript queryflash, only BankA and EEPROM are listed. Any idea what has caused this and how to fix it?

Thank you.

Hello MCUXpresso IDE Support, 

Reminder from our side. 

We are using LPCXpresso 54628 development kit OM13098 for our development purpose. We are also facing some issues while flashing firmware from USB powered cable. 

We are not able to flash firmware from USB and facing same issue which has been mentioned into this thread. 

Anyone has any idea like is it proper way to provide supply from USB through CPU and also flash firmware using that same interface via MCUXpresso tool?  Let me know if any other recommended option for same to flash firmware. 

Regards, 

Ritesh Prajapati

So this raises the question as to what you have actually programmed into your board?

But that aside, you could try doing a mass erase via the "debug mailbox" that is implemented on these parts. There is a script that can be used to do this inside the IDE install directory at "/ide/bin/Scripts/LPC5410xMassErase.scp".

Instructions on how to use this script can be found at the top of the script file (which is basically just a text file).

Note that you will need to ensure the LPC-Link2 is booted first, which can be done using the "boot_link2" script in the /ide/bin directory (as per MCUXpresso IDE v10.0.2 User Guide section 14.12.4", Manually booting LPC-Link2").

Whether this will work is of course dependent on how badly you have "locked" your part.

Regards,

MCUXpresso IDE Support

I am so grateful for your advice. It took me several attempts using different combinations of redlink commands (for whic I could not find any guide documents) to mass erase the flash. I have now recovered the board (using external Link2 probe), and am trying to recover the on-board Link2 Probe.

[lpcxpresso_supp]

I'll say again - you cannot use the LPCScrypt utility with the LPC54608 MCU.

LPCScrypt will only communicate with the LPC43xx MCU that is used in the debug probe.

Also - I strongly recommend that you do not try using the mbed firmware with this board unless you actually intend to develop using the mbed online tools and use the drag'n'drop mbed mechanism for programming.

I would suggest that the next thing you need to do is try booting the board into ISP mode before you try making a debug connection : https://community.nxp.com/message/630748 

And then follow the instructions I gave you in my previous post.

Regards,

MCUXpresso IDE Support

[hosseinragheb]

Thanks again for your response.

Unfortunately the MCU does not enter the ISP mode, I followed the steps suggested, alongside the reference manual (UM10912 - Chapter 3: LPC546xx Boot process - Rev. 2.0 - 26 July 2017), specifically Table 5. I've tried all combinations. My guess is the value written at ECRP has locked the use of ISP mode (UM10912 - Chapter 42: LPC546xx Enhanced Code Read Protection). Table 1020 specifically gives the details.

Also the manual specifically says: 

Remark: If SWD (17:16) is DISABLED, ISP Entry from ISP (15:14) is DISABLED, and ISP
Entry from Bootloader (13:12) is DISABLED, the IAP Mass Erase can still be used to
erase the entire Flash to recover a device.as long as the OTP MASS ERASE is
ENABLED. This will require a programming interface to program the Flash once it is
erased.

That's why I'm looking for a software/tool to access and write proper values at ECRP.

[lpcxpresso_supp]

First of all, note that LPCScrypt is not used for accessing the LPC54608 chip on your board. LPCScrypt can be used to program debug probe firmware into the built-in LPC-Link2 debug probe (which is based on an LPC43xx). Trying to program applications for the LPC54608 using LPCScrypt is thus very likely to result in a non-functioning debug probe!!!

Anyway, I suggest that you proceed as follows...

First of all, close down the IDE and disconnect your board from all power / USB sources and ensure that you have a link fitted on header JP5 ("DFU-Link").  This will allow the IDE to softload the probe firmware into the built-in LPC-Link2.

Now connect the board back up to debug port USB connector (J8) and also to the power USB connector (J1) - sometimes the board will not get sufficient power through USB alone (particularly if the LCD screen is being used or). If at all possible, I would suggest powering the board via a powered USB hub.

Now manually book the debug probe, as described in section 14.12, "Using and troubleshooting LPC-Link2" of the MCUXpresso IDE v10.0.2 User Guide (in particular section 14.12.4).

Please confirm at this point that the LPC-Link2 appears correctly in the Windows Control Panel "Devices and Printers"

Having done this, open Task Manager and make sure you have no executables of the following form running:

• redlinkserv
• arm-none-eabi_gdb*
• crt_emu_*

Now start the IDE,  and try debugging one of the example projects. If the debug session still fails to start, please post the debug log that you now see.

Regards,

MCUXpresso IDE Support

Thanks for responding. As you've mentioned the on-board debug probe is not functioning any more, so I used an external LPC-Link2 probe instead. Following the steps suggested did not change the outcome though (see the log below).

I think what has caused all this is that I have mistakenly written (an example binary file) over the on-chip memory (at 0x0 rather than BankA for instance) using the LinkServer GUI Flash Programmer. Now the question is how to write the original chip firmware back to its appropriate location? I have downloaded "lpc4322_bl_crc.bin" and "lpc4322_lpc54608xpresso_if_crc.bin" from Updating LPCXpresso firmware - | Mbed 

and can obviously use LPCScrypt to program_CMSIS lpc4322_bl_crc.bin, but then I cannot program lpc4322_lpc54608xpresso_if_crc.bin. Any ideas?

Having read about ECRP (Enhanced Code Read Protection), I notice that its value at 0x20 is currently 00000000 (lpcscrypt memDisplay 0x00000020). I think the current ECRP settings (bit values) stop many possible interactions such as ISP, SWD, Flash erase/write. Now, I need to write the new value 0002A83F at 0x20 to enable ISP boot up possibility and SWD. Any idea how I can do this please? I tried LPCScrypt commands below, but no luck yet (even generated the binary file containing the word I need 0002A83F, called ECRP0x20.bin below).
