When using an external FTDI cable for OTP burning or image downloading to external memory, it’s important to set the FTDI cable’s latency timer to less than 10 ms.
Follow these steps to change the latency timer:
Open the Windows Device Manager.
In the Device Manager, expand the list of COM ports.
Right-click on the COM port relevant to your setup and select Properties.
In the Port Settings tab, click Advanced.
Set the Latency Timer to a value less than 10 ms.
Click OK to save the changes and then close the Device Manager.
Hint
You can find a visual reference for the “FTDI Latency Timer” in Figure 24.
You can burn data into the SPI flash using SST (SPI Serial Transfer) over a single UART connection. However, there are specific pin configurations you need to follow for this setup. When programming the SPI flash using 2-wire UART, you will need to perform OTP (One-Time Programmable) programming. This is because the default SPI pins are shared with the default UART pins (P0_0/P0_1).
For detailed information on how to configure the pins and perform this process, please refer to the section 6 in the AN-B-072.
Use of the Single wire UART to download code in SPI flash is also possible, The figure below showing the default configuration on Prodevkit and SmartSnippets™ Toolbox:
