TPS65982: TPS65982 firmware image information request

George Huang
Prodigy 250 points
Part Number: TPS65982
Other Parts Discussed in Thread: HD3SS460,
  1. In TPS6582 datasheet Figure 79, control from 65892 to HD3SS460 is  is 65892-HD3SS460 ( GPIO_0->AMSEL, DEBUG_2->POL, GPIO_3->EN). While in TI EVA design tidrn40.pdf, it is using 65892-HD3SS460 ( GPIO_0->AMSEL, GPIO_2->POL, GPIO_1->EN). So how can we choose a correct firmware to match with “65892-HD3SS460 ( GPIO_0->AMSEL, DEBUG_2->POL, GPIO_3->EN)” mapping? Or our software team needs to make modification for the source code and recompile to match this hardware mapping?
  2. Do you have any information for our software team to guide them how to compile the TI firmware into our MCU/SOC? (in out case, we use Xilinx Ultra-Plus Zynq SOC with ARM core, should our software team needs to compile the TI image into their OS and download image through 65892 I2C slave? Or some other way to ease this process?).

Thank you.

    1. The TI design that you are referencing is using the HD3SS460 with TPS65986, not TPS65982. The are also various other devices connected in the TI design schematic so the GPIO selection is up to you for application purposes. If you are using the TPS65982, the datasheet recommendations will work for the GPIO configuration to the HD3SS460, so I recommend following that setup from the datasheet, unless you plan to use it for dock application exactly like how the TI design shows.

    2. That is one option you could use for programming the configurations via I2C. However, you can also program the configurations via SPI Flash as another option. In addition to the datasheet, I would recommending also reading and going over the TPS65892 Firmware User's Guide, Host Technical Reference Manual and the FW Update From Embedded Controller Over I2C app note. You can find the links for these documents below.
