As the project evolves, I have to change boards and I am facing issues to boot: absolutely no output on the serial console (USB virtual COM port), not even from Barebox. Previous working configuration: - SD card image produced by Buildroot with Barebox as the bootloader - Terasic ADC-SoC demo board, booting from the SD card. https://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&No=1061&PartNo=1 Current non-working configuration: - Eclustra Mercury+ SA2 module, also with a Cyclone 5, plus SDRAM, RTC, QSPI flash, etc. I think that the main difference between both Cyclone 5 chips is the size of the logic section is bigger on the module. The module has more RAM. https://www.enclustra.com/en/products/system-on-chip-modules/mercury-sa2/ - Enclustra ST1 demo baseboard. It has a JTAG port, should this information be of interest. https://www.enclustra.com/en/products/base-boards/mercury-st1/ I the current configuration, I get no output on the serial console. What I did: - I checked the hardware configuration (switches to select booting from the SD card and USB config) with a bare-metal application provided by Enclustra. - I used Enclutra's .dts and .dtsi files, which differ very slightly from the Linux kernel tree files. - I checked how the SD card is connected: to the exact same pins in both configurations. - I had a look at Barebox menuconfig, but nothing caught my eye. So, now I'm stuck, and I'm looking for some guidance. David
