Sk Pro v 1.2 Won't let change readout protection level

Post by misticmight »

Hello all! Currently I am trying to reflash an SK Pro board for use as a cnc driver. It is connected through an ST Link v2 and connecting to the board with no issues.

On the connection page it is listing itself as Device ID: 0x413, Revision Idea: Rev Y, flash size: unknown.

On the Options Bytes page the only user configuration option bytes selected are nRST_STOP, nRST_STDBY, and WDG_SW. Read Out Protection is set to lvl 1, BOR Level F: OFF, R: blank grey. All individual sectors show now protection.

On trying to change the readout protection levels it gives the error: "Can Not Read Memory! Disable Read Out Protection and Retry", and above it in the command window it reads "Could not set Option bytes! Please reset the target and retry." The connection information is listed below:

18:53:04 : ST-LINK SN : 440025001500004A4735544E
18:53:04 : V2J29S7
18:53:04 : Connected via SWD.
18:53:04 : SWD Frequency = 4,0 MHz.
18:53:04 : Connection mode : Normal.
18:53:04 : Debug in Low Power mode enabled.

Update the stlink firmware. And try to change the connection mode if the nrst pin is connected.
Other way try to enter in bootloader mode to use serial.
