      @Sharmila GPIO0 must not be low all the time. It must be held low only for a moment. Because GPIO0 is a boot strap option for choosing between UART download and normal operation. Please refer to the datasheet and search boot strap. And also can you please post a snap of your newly designed board please?

            @Sharmila Reviewed your schematics. Have the following doubts

            1. Is this a USB receptacle?

            1. Didn't find any option where you can pull the GPIO0 low and bring it back to normal state. Did you have a jumper connection or button between GPIO0 and GND?

                The reason I wanna use online tools only is because, I have been using my company's lappy and I am restricted to install any other Softwares. So, online tools will be an easy way for me. by the way I have found another way too. EasyEDA provides an super easy solution for creating custom PCB shapes. It really came in handy for me.

              • Hi all,

                I recently came across this post where they have shown photos printed on PCB in high resolution. I would like to know how to add this kind of photos to the silkscreen layers of the PCB in Eagle/Altium.

                Adding such kind of photos will be attractive for beginners and also can be used for educational purposes too.
                Please let me know in case anybody knows.

              • @kowshik1729 I think that might not get since the platform is not opensource! but they provided everything you need to develop a system with that.

              • @kowshik1729 Carrier board schematics for SoMs will be always available as they need to be modified as per customer application, however SoM design files are hard to get unless the H/W design is truly open-source.

              • @salmanfaris Actually the schematics files you've mentioned are the same files which I've got from them. They are carrier board design files.😢
