Hello Everyone!
This series will introduce basic support (SD and UART) support for Texas
Instruments J784S4 EVM.
For the whole series:

However, one thing I noticed is that with upstream TF-A I do get the following
errors:
NOTICE: BL31: v2.10.0 (release):v2.10.0-76-g02091541d
NOTICE: BL31: Built : 18:13:08, Dec 14 2023
ERROR: Failed to get response (-19)
ERROR: Transfer send failed (-19)
ERROR: Unable to query firmware capabilities (-19)
While with latest TF-A from downstream TI BSP (both 9.0 and 9.1 use the same
versin) I do not get any errors:
NOTICE: BL31: v2.9(release):v2.9.0-614-gd7a7135d3
NOTICE: BL31: Built : 18:40:38, Dec 14 2023
What version of TIFS are you running? Not getting a response usually
means firmware is dead or we're not using the right thread to talk.
In this case the early versions of TIFS/DM for J784S4/AM69 had
a bug where the "query firmware capabilities" API was left disabled.
This is fixed in the next version of firmware, this error message
is harmless today anyway (no LPM yet).
