Part Number: BQPRODUCTION
Hi,
What I want to achieve is to flash my BQ27750 in production.
I have completed all the following steps:
1. Find ChemID using the "Gauge Development Kit"
2. Performing a learning cycle on my PCB
3. Generated .srec file in bqstudio (updated to BQSTUDIOTEST after reading this post: e2e.ti.com/.../716508)
I was then looking over this video (https://training.ti.com/bq40z50-setup-and-going-production and was reading here (e2e.ti.com/.../2368783)that when you want to flash the fuel gauge in production one should use the bqProduction SW and the EV2400 (since reading from you website "EV2300 is not supported for new designs" )
We then purchased a EV2400 and flashed it with the latest FW (0.28) as suggested by the post.
When I now try to connect to the EV2400 I get the same fault as described in the earlier post i.e "Communication adapter not supported", furthermore when I now connect my "Gauge Development Kit" my fuel gauge is no longer automatically detected...
Overall I have to say that nothing has been working straight away using your fuel gauge+tools. Have solved most of the problem so far by FW updates, SW updates and reading workarounds from the forum but now we are stuck.
So first, what can I do to make our "Gauge Development Kit" work again?
Second, how can we get the EV2400 and bqProduction to work? (On this point I would not like to have the answer "Buy a EV2300" or use bqStudio since you cant expect a manufacture to use bqStudio where they have full access and can mess things up ).
Regards
