riscv64 - SiFive Unmatched regression?

riscv64 - SiFive Unmatched regression?

[Alex]

Hello!

Running into a potential regression on the SiFive Unmatched.

These images function as expected:  (u-boot Nov 2021, OpenSPI 0.9)
https://github.com/haiku/firmware/tree/73e14d53b45a6b74/u-boot/riscv64/unmatched

UART output, no issues.



The latest master u-boot images no longer boot from the SD card in any testable configuration:

  * master as of today + OpenSPI 0.9
  * master as of today + OpenSPI 1.0

The symptom of "no longer boot" is the Unmatched showing a bit of gibberish on the UART.


All SD cards provisioned using identical known-good steps documented by u-boot.

Please ignore.  I was down to bisecting with multiple gcc toolchains building u-boot
when I realized one of my (seemingly good) MicroSD cards were refusing to boot in the
Unmatched.  I swapped cards and things started working as expected.
