We need to implement program of Non Volatile memory in BQ50Z60RHBR, store customer's configuration from file into the device. Could you kindly provide description how to do this?
Are you referring to bq40z60? What file format do you have? gg.csv or srec? You can use our bqStudio with EV2300 or EV2400 to import the configuration file and program it to the gauge. Click the Firmware tab in bqStudio for srec or Data Memory tab for gg.csv.
We have srec file and also our customer will use srec file. We're requested to implement the programming of the device on our device programmer for mass production.
But we need to know how to store content of the SREC file into device. Customer will not use bqStudio with EV2300 or EV2400, but our programming tools. And we must write the algorithm for our tools.
You can do a hex dump of the data flash memory using bqStudio and use the hex dump file to program the settings in production. The hex dump can be executed from bqStudio >> Data Memory.
OK, and how is the HEX file programmed into the device memory? Via I2C, SPI or other interface? What is device's address during the programming. Do you have any complex programming specification?
Thank you for your response. I can only repeat question if there is available programming specification - low level description of the read/write commands and overall protocol ... The application note you linked describes only programming via TI's SW tools, but low level protocol is hidden.
PS: another customer sent request to implement support, so the case becomes to be hot. If necessary contact me directly via e-mail.
Frantisek,
The 44 command was implemented to allow the user to update the data flash with a uC. Use the 44 command to setup the starting address (which is 4000H) and them use the 44 command to write data to the flash 32 bytes at a time. Will their uC support this option?

Our programming tools can support any SMbus command, this is only question of the application SW. May be you can check our WEB site (http://www.elnec.com) to know more about our programming tools.
For the mass programming in production the customer will our programming tool, not his own solution.
