With the latest firmware compiled from the Master Branch, the brute bypass & idcode scan reboot the target device.

Could you explain why do you closed this issue (I suspect it was not an issue with HydraFW but it will be better to add an explanation) ?

ghecko commented 5 years ago

Yes, when I used brute command on Hydrabus the target device reboot on each try. I can not reproduce this specific issue on another target device; this is why I close the issue.

Thanks for the details if you could provide details on the target it could be interesting for other users ...

Yes, the target is a 4G modem Huawei B525s-23a (processor Hi6932M2GFCV100). If someone find the datasheet I want it !

Thanks for the feedback but unfortunately no public doc exist (today) on this CPU/4G Modem especially related to JTAG This issue is closed and you can reopen it if you have a datasheet or you have found a bug in JTAG brute scan
