broadcom port for raspberrypi4b often corrupts SDCard #5706

Open jerryneedell opened 2 years ago

jerryneedell commented 2 years ago

I am able to build and load CP to a raspberry pi4b but very often when I disconnect the USB port (and power) the next time I try to power it up, the SDCard is corrupted . The Green LED blinks 4 times and the Pi does not boot. If I reflash CP to the SD Card, it boots OK.

With the current build, the CIRCUITPY drive does not mount so I can't "eject" it before unplugging. Is this related? Is there something I should be doing before unplugging to prevent this?

It also happens when I power the 4B via a power only USB supply. It boots OK but after unplugging and replugging, the SDCard is corrupted.

So I think the problem caused by resetting the SD card pins is fixed.

I'm still seeing occasional init problems. Here are the debug logs of the init. From my rpi_flash_dmb branch.

While working on the SPI issues I noticed that when the PI4B would corrupt my SD card, I would often get directory entries that looked similar to this one:


Adafruit CircuitPython 7.2.0-alpha.0-120-gaee80d67b on 2021-12-14; Raspberry Pi 4B with bcm2711

corrupted broadcom flash2

It looks to me like the output meant for boot_out.txt is overwriting the root file directory.
