Hi Goodix,
we use the Goodix GR5515IGND chip with SPI display and our custom board. SDK version is GR551x_SDK_V1.7.0.
My question is about the bootloader. One of the requirements for the product we are developing is the visualization of the update process.
During the DFU process, as far as I understand, the MCU will jump into the bootloader. Plaese let me know, is it possible to change the bootloader code (and is there one) to add, for example, an indication (on SPI display) of the update process?
thanks!
