Re: Lenovo yoga c930 NM-B741 Doesn't boot or charge USB type-C controller issue.
Hi. No that will not work. The power delivery controller is a Cortex M0+ cpu which is an ARM design.
The details of the programming interface are well documented but are JTAG / SWD interface based.
A suggestion is to consider a low cost Cypress kit from which you can detach the front side of the pcb to retain the usb to swd bridge for this exercise.
For example, CY8CKIT-059 could work.
You can confirm the above details in the Cypress user forum for the noted controller chip but fairly confident you can program with this method.
A key concern remains on whether the firmware is protected or not inside this CPU. If the firmware is protected from read outs, then the tool and process will not work.
So summary is to buy this low cost kit, load their free tools, use the kit to understand the programming of the target cpu. After this, break off the programmer portion of the pcb. They build this slim ruler type kit for this purpose. Then wire onto your true target Cypress cpu and repeat.
Review the schematic of the kit and this target power delivery controller for the programming interface.
