@Smokingenius when powering the target board from the Rigol programmable power supply and trying to enumerate the JTAG pins using Arduino do you have common ground in the circuit? Sorry...

@CCASTM Could you please provide some feedback with regards to this issue?

@ST-dot-com I see that there is some communication issue - I can not receive a meaningful response neither from PSIRT via email nor here at github.

@stmicroelectronics-github Can you please provide your feedback for this issue? When are you planning to publish the CVE and migrate the fixes?

Hello @ALABSTM , Since this issue results in a buffer overflow affecting application security are you planning to publish a corresponding CVE? Best regards, Szymon

The main factor to consider here are the voltage levels used by the target and probe. Generally a range of bidirectional level converters are available on the market from different...

This should do the trick for most configurations, please consult documentation from TI to assure it meets your particular requirements. [https://www.ti.com/product/TXB0108](https://www.ti.com/product/TXB0108)

This is currently not supported but I'll consider this in a spare moment. I don't have spare cycles at the moment but hopefully I'll be able to look into this.

Hi @BM120395 , Can you please provide more details? - what are the target chips? - what is the JTAG voltage for the target chips? - can you elaborate on...

Hi @BM120395 , Thanks for the provided information. Personally I would consider adding capacitors, e.g. 0,1 uF between both VccA and VccB and ground. Also a pull-down on the OE...
