[ISSUE] ST-link claims Read Out Protection is enabled

[shuffleznl]

Bug Description

First of all thanks for your great work, doing what Biqu/BTT failed to!
Makes me very humbled to see the work individuals put in to support others.
I'm not sure if to post here, as it's not a bug with any of your doing at all :)

Issue appeared after restarting the board (it was printing before, so FW/SW was running well).
Rebooting the board didn't start nor did it read from SD (tried several FW's).

Upon connection of ST-link (swapped SWCLK & SWDIO to be sure) it reads Device, DeviceID, RevisionID, but Flash Size is reported 'Unknown'. Also a warning is thrown; 'Can not read memory! Disable Read Out Protection and retry.'

Cannot reset Option Bytes Read Out Protection from 1 to 0.
Full Chip Erase is also 'protected' because of 'Read Out protection is activated' warning.

Additional Information

EDIT: Updated the ST-link FW and checked latest version of ST-Link.

@shuffleznl Are you using the ORIGINAL or OFFICAL ST-LINK-V2 device or a clone device? Which BIGTREETECH board are you trying to talk to?

[GadgetAngel]

@shuffleznl Try to recover the chip by using the system bootloader:

Force boot0 pin to be 1 and force boot1 pin to be 0 at power up, start bootloader then connect USB and program the chip with DFU programmer. You can download the DFU programmer https://www.st.com/en/development-tools/stsw-stm32080.html#

can you help me please ? i used a stlink V2 clone
is it possible that my GTR is dead?

Instead of loading only the bootloader file, try flashing the "Bootloader+firmware" file. This file contains the Micro-SD card bootloader and the original firmware that was delivered when you got the GTR board fresh from the factory.

Also check to see if the micro-SD card reader is even working. I have seen other users say that the micro-SD card reader has bent pins. Use a flashlight and check to see what the micro-SD card reader's input slot looks like. Are all the pins flat in the slot?

On Linux, you could use the STM32programming Utility. They make a version that will run under Mint Linux. I use that one when I am on my Linux laptop. The last time I used st-link from GitHub (if I am remembering correctly) I had trouble with flashing the MCU boards. If you must use st-link from GitHub then check out their current issue and closed issues (https://github.com/stlink-org/stlink/issues). Someone else might have experienced this issue and might have solved it. You might have to rollback to a different version of st-link (https://github.com/stlink-org/stlink/releases)

I know you are using a V2-clone on Linux but I highly recommend you buy and official ST-LINK-V2. STMelectronics has some proprietary stuff in that device that the clones do not have.

If you own BTT boards, it is worth the investment to buy a genuine ST-LINK-V2. They are around $55 (https://www.amazon.com/Microcontrollers-circuit-debugger-programmer-emulator/dp/B00C7WDTLG). You have to think of buying an ST-LINK-V2 original as if you need a specialized set of Wera Allen keys. For example Wera TORX Allen Keys cost around $55 on amazon (https://www.amazon.com/Wera-05024480001-Multicolor-L-Key-TORX/dp/B07B7XWJZ6).

Apologies for abandoning the thread, I moved to SKR board (until it fried), on different (non-BTT) HW now.

Can confirm; Wera and original ST-Link are both worth it.
