Here you can find a wide variety of types and values of electronic parts from the world's leading manufacturers. The BMR-3135A parts manufactured by SANYO are available for purchase at Jotrin Electronics website. Hello guys, I have few batteries with BQ8030 which are released by Sony/Sanyo, there is no datasheet for this chip. Hello, I have a strange problem with dell inspiron battery with bq8030 sanyo chip. #SANYO TOOL RESET BQ8030 DATASHEETARCHIVE FOR WINDOWS 10#WinRAR for Windows 10 Description WinRAR is a powerful utility for creating. Profit And we've made the educated guess that Step 2 is really 'Send 0x? To 0x71' so we're pretty much done with the disassembly as 16 bits is way within the realm of bruteforceability and since I had another sacrificial board as well as a battery pack running SANYO firmware I had everything I needed to attempt it.Sanyo Tool Reset Bq8030 Datasheet Archive. #SANYO TOOL RESET BQ8030 DATASHEETARCHIVE CODE#Disassembly A couple of hours of staring at unfamiliar assembly code later, here are the relevant parts for entering the Boot ROM with annotations.Ĭmd_handle_70: *snip* move r3, access_level and r3, # 0x40 cmp r3, # 0 don't even bother if access jeq cmd_handle_71 flag 0x40 is missing *snip* calls smbSlaveRecvWord move r2, (i3, 0x19) smb_word_LSB move r3, (i3, 0x18) smb_word_MSB cmp r3, # 5 jne wrong_pass cmp r2, # 0x17 is 70 0517? Jne wrong_pass *snip* (prepare leaving the firmware safely) calls bootrom_execute So now we know pretty much what we need to do. How much of the firmware survives is another question. So when in doubt and you have nothing to lose, act like a caveman, I guess? The only good thing about this method is that even if you have 0 knowledge about whether there even IS a method for entering the Boot ROM in the firmware let alone what it is there's still a high chance that you'll get in. Was there high voltage on VCELL+? Was it just ESD? But I did manage to reproduce the result on another chip using the same procedure. Did messing with Pin #28 even have an effect?Ĭould it just have been the erratic resetting of the chip that triggered the malfunction? Did I short VCELL+ to Pin28 while messing about? The good news though? (If we're lucky) We get 99% of the firmware, and thanks to we have a (zip) for it. (I wasn't really bothered by the chip dying as this was one of 2 sacrificial controller boards I kept just for messing around with.) And the results? Apparently we can corrupt (ideally just) the first couple of blocks of flash if we bully PIN #28 while the chip is trying to start up. Is the chip fried? It's at this point that I coded up the flash tool to try and read the flash contents. #SANYO TOOL RESET BQ8030 DATASHEETARCHIVE SERIAL#Modem Telecom Fttc Sanyo Tool Reset Bq8030 Datasheetarchive Helpsmith Serial Keygen Filmora Antivirus Test Results 2009 Hyundai. $ smbusb_sbsreport SMBusb Firmware Version: 1.0.1 - Manufacturer Name: ERROR Device Name: ERROR Device Chemistry: ERROR Serial Number: Manufacture Date: 1980.00.00 Uh-oh.

I have no logical explanation as to why I came to this decision. How about I try to abuse N/C pins instead. Or maybe there's no such combination at all. So maybe we have to set multiple pins into multiple states for it to work. But maybe pulling some pin high or low during reset will get me somewhere.
