Try enabling CONFIG_DEBUG_LL to see if you get some early output from barebox before the UART driver was probed. barebox might not work under a "trusted" TF-A, because it isolates some peripherals behind vendor-specific secure monitor calls. I intend to add support for these, once upstream TF-A has SCMI support. For now, you may be better off using the flash tool like it's intended and write vendor TF-A and vendor U-Boot to RAM and then use those to flash barebox and TF-A to eMMC. See FlashLayout_sdcard_stm32mp157c-ev1-basic.tsv[1] for an example.
