Hello, I am experiencing a total boot failure on the GameForce Ace handheld console (Rockchip RK3588S) when trying to run mainline U-Boot v2026.07. The device fails to initialize or display any output during the initial handshake. Unfortunately, due to the tightly integrated form factor of this handheld device, it is exceptionally difficult to break open the casing and wire up a UART serial console to capture early boot logs. The target operating system (Batocera Linux) environment is running the mainline Linux 7.1.5 kernel. Given the complete lack of visible console output, I wanted to check:
1. Has the GameForce Ace board target been actively tested with the v2026.07 release? 2. Are there any specific or updated build instructions, BL31/TPL/SPL combinations, or proprietary Rockchip firmware binary requirements (rkbin) needed for this release that may differ from previous versions? For reference, the build configuration used was: gameforce-ace-rk3588s_defconfig TF-A / BL31 version: rk3588_ddr_lp4_2112MHz_lp5_2400MHz_v1.21.bin / rk3588_bl31_v1.54.elf Compiler: GCC 14.3 Linux 7.1.5 uses the rk3588s-gameforce-ace.dts Any guidance on known regressions regarding this target, or recommendations on how to isolate the stage where it hangs without a hardware UART, would be greatly appreciated. Best regards, Daniel
