SD card init fails every other boot #57

Open xdissent opened 4 years ago

xdissent commented 4 years ago

I don't really follow the "ping/pong" sd card initialization seen here and here but it's failing to enable SD ever other boot.

A successful boot looks like this for me:

--->probe spend 5 ms
Enables SDCARD
ping
gpio_request lable = cmd_gpio gpio = 43
gpio: pin 43 (gpio 43) value is 1
gpio_request lable = cmd_gpio gpio = 48
gpio: pin 48 (gpio 48) value is 0
gpio_request lable = cmd_gpio gpio = 43
gpio: pin 43 (gpio 43) value is 0

and then it hangs at:

[    1.459076] Waiting for root device /dev/mmcblk0p1...
[    1.794332] dwc2 dwc2:  ++OTG Interrupt: A-Device Timeout Change++

The LED never shows any blue on a failed boot, just flashing yellow.

From what I can tell, count: 1 means it works, count: 2 means it hangs. Here it looks like if count :1 it immediately sets count: 2. Any idea why?

Could you check line 50?

elseiftest\"${soctype}\"=\"T20X\"&&test\"${flashtype}\"=\"EN25QH128A\"&&i2cprobe0x40;then\+

Try to remove this part && i2c probe 0x40.

Problem: the bootloader didn't identify more than two times the same ' if then ' and then the ping pong starts.

I got this a lot with rc5 release. Never managed to solve it. And never had any luck on my neos building the master branch.

Be good if some others got involved to get the project moving again. Its a shame its stagnated.
