Other Parts Discussed in Thread: DLPC3439
Referring to the schematic diagram, a USB bridge circuit(U48) was designed,
but the USB to SPI conversion was not implemented.
(1) I hope you can provide the configuration data of the chip below for reference.
I am using the CYPRESS tool below to write configuration data.
USB Serial Configuration Utility
(2) I hope you can provide the method steps of writing the FLASH program in SPI mode,
as well as the corresponding writing tools and usage methods.
Thank you very much !
