Recovering a Bricked SSD with JTAG and a Raspberry Pi
- cozzyd 6y agoStrange that they'd bother to disable the UART interface if the JTAG interface is open.
- fulafel 6y agotldr: convinced the firmware to retry erase, instead of refusing to initialize.
- brokenmachine 6y agoNice article. Once you've found the JTAG port, is there a command to dump the entire code? How do you tell what architecture the chip is, or does the JTAG output tell you? Was the writer just halting the chip randomly and looking at what's at that memory location? >SSD vendor (who shall remain nameless) Doesn't this mean that no customers can secure erase their devices without bricking them? They should definitely be named...
- brokenmachine 6y agoIf anyone cares, I think the way to dump the code is something like this (addresses will depend on device): after "halt" from OPENOCD type dump_image ffff0000.bin 0xffff0000 0x10000
