Enable UART0 on STi7105
Budget: €20 – €170 EUR
My STMicroelectronics STi7105 board shipped with every serial port but UART0 disabled, leaving me without a console for diagnostics. I have the complete original firmware, yet UART0 is still inactive. What I need is:
• A patched dump that will work without doing any other step, so just press enter to stop U-Boot
or we go with these other steps below
• A freshly compiled second U-Boot that brings UART0 up as the primary console.
• Guidance on the required “glitch” (boot-mode workaround) so the box starts from this new U-Boot image.
• A brief explanation of any extra utilities you rely on; I can procure whatever is missing.
Acceptance criteria
1. Power-on messages appear over UART0 at 115 200 bps (or the rate you configure).
2. I can interrupt U-Boot, reach the prompt, and run basic commands.
3. Your written guide reproduces the result on a clean Windows workstation.
You will have remote access to the full source tree and existing binary dumps if that speeds things up.
