Troubleshooting BootROM Errors: Waiting for GET and STB UART Receive Full

If you're experiencing BootROM errors, particularly when waiting for a GET request or encountering a situation where the STB (Set-Top Box) UART receive buffer is full, follow these steps to troubleshoot and potentially resolve the issue: If you want, I can:

The error often appears even at the correct baud rate. However, try these common STB baud rates sequentially:

Use a logic analyzer (e.g., Saleae) to snoop the STB’s TX line during boot. The BootROM often prints a string like "Please send get command..." at boot. Match that speed. Troubleshooting BootROM Errors: Waiting for GET and STB

This error is almost always host-side noise or incorrect protocol, not a dead SoC. Start by eliminating all serial chatter during BootROM window (first ~300ms after reset).

Would you like a sample script to automate the clean handshake recovery? Use a logic analyzer (e

Power the STB from a linear power supply (not a noisy switching wall wart). Add a 100µF capacitor across the STB’s power input to smooth ripple.
