I was mainly interested (but didn't wrote it directly) in details > for that at91 SOC/custom design Jean has mentioned - "I've design a ser2net + > power switch arround a at91 SoC" (How could one handle 20 serial ports with > that SoC? Multiplexing? etc.). no toady we try to prepare a openhw arround a sam9x25 with a sponsor we will handle - 6 uarts - 6 power switch - gpio extender - microsd - usb host - usb device - ethernet dual (realibility) - power mesuremenet
I've some handmade with are the same arround 9g20 ref board + power board and calao hw. THe idea is not to handle 20 serial ports per system but 6 I've try other design we seperated serial (FPGA) and power control but it's more expansive at the end and does not provice gpio expander or adc so not very intresting to remove reset/switch and mesure anything Everytime you will need to add external equipment that are expansive Best Regards, J. _______________________________________________ Celinux-dev mailing list Celinux-dev@lists.celinuxforum.org https://lists.celinuxforum.org/mailman/listinfo/celinux-dev
