*IAP upgrade routine:
|
|
*Support serial port and USB for FLASH burning
|
|
*
|
|
*1. Use the IAP download tool to realize the download PA0 floating (default pull-up input)
|
|
*2. After downloading the APP, connect PA0 to ground (low level input), and press
|
|
*the reset button to run the APP program.
|
|
*3. The routine needs to install the CH372 driver.
|
|
*Note: FLASH operation keeps the frequency below 100Mhz, it is recommended that the main
|
|
*frequency of IAP be below 100Mhz
