I hope that it will work because I can see all the battery detailes in the PM program. Another one question that I seems to erase one bq it is indicating only ACK on 0x0 bq8030dbt datasheet 0x1, can I download there a software from another BQ bq8030dbt datasheet datasheeet to waste it out? Seems that mine does decode it different. The EC manages the bus by itself and only provides an abstracted interface bq8030dbt datasheet accessible to drivers.

Ah yes, that message was fixed quite a while ago but the windows binary release is a bit outdated. Viktor, did you saw these bq8030dbt datasheet while got in bootrom? If you are searching for battery protection, check here: Tried with root and it works.

Hello, Glad you found it interesting! Ask a related question What is a related question?

I managed to bq8030dbt datasheet 85Wh battery. Viktor September 14, at 1: For bq20z90 in that case it would be triggered the fuse as mV is deemed bq8030dbt datasheet critical. Bq8030dbt datasheet need to perform some hardwiring.

The datasheet of the micro should help. In overload, short circuit in charge and short circuit in discharge conditions, the bq turns off the FET drive autonomously, depending on the internal configuration setting. You may want to set that port’s pin to an input when you don’t want to keep it at a certain state ie. Can’t help there are at all, sorry.

My second question is whether the firmware dump from that battery will be usefull for the new replacement chip BQ20Z90? By looking at the sources it seems your code is pointing to device “0x04b4,0x”. Got it bq8030dbt datasheet communicate.

Mateusz Grzywacz December 23, at bq8030dbt datasheet Now the T61 bq8030dbt datasheet that the battery can’t be charged due to normal wear and of course can’t be used. Try flashing the firmware again. And then some 01 00 00 at 0x I have searched the forum but found nothing. Congratulations on the post.

If the answer of the question N2 is NO datasheeet the only option left is bq8030dbt datasheet use bq8030dbt datasheet battery like a source for the firmware dump I know that it is not recommended. This product continues to be in production to support existing customers. Binary and hexadecimal numbers, byte order and so forth.

BQDBT – Texas Instruments

To use the dump from other similar or what? When the first instruction is a NOP I’m guessing the chip thinks it’s blank and enters the boot-rom. I’ve always wondered how boot ROM datasehet loaded onto these chips in the first place. Is it really possible bq8030dbt datasheet recover in such way bricked chip with a new datasheft firmware of same version, say got from another source? When replacing the cells, the cali bration data and the serial number were lost.

I started to mess with the bytes even more, and then. So if the function is active in your battery then bq8030dbt datasheet need to write the authentication keys X October 4, at 3: Once you’re in the boot rom you can read the corrupted, first block missing firmware and since you’re only missing initialization code at the start you can still disassemble bq8030dbt datasheet to extract the password s that you can then use on other batteries.

datasheet for BQ8030,BQ8050

In reply to Paul Woo:. That area is checksum protected and I haven’t really looked into it.

bq8030dbt datasheet Can you share your eeprom dump? Viktor August 15, at 7: Tried to send image directly with address 0x00 so now it is a brick. Not entirely sure since I don’t know how the clear occurs exactly.

Viktor November 25, at It’s not clear in the disassembly any related code for delays. I didn’t do anything like that, no. Viktor December 27, at 2: So supposed it may bq8030dbt datasheet another access level related command. Below is bq8030dbt datasheet of my actual battery, disassembled.
