[Bug]: Both OS on emmc and tf-card boot not every time #460

Closed sevocrear closed 11 months ago

What happened

Hello everyone,

I have boot and connections problems with k510.

After powering on the kendryte K510, it boots not every time. I need to push K2 (reset) button several time in a row in order to make it work and boot successfully. Also, the same happens even if I boot not with emmc, but with tf-card.

I either get black screen of k510, or the broken logo screen.

Initially I thought that the problem is in the power supply, so I tried different adapters 15 W, 20 W, 25 W. But it didn't fix the issue.

Also, despite the fact that it struggles the boot, when it boots successfully, I can't work with the "screen". The terminal is slow and laggy (while having serial connection with k510). It's impossible to write commans or change the files with vim, for example.

k510 connection (power and UART): image

There are some photos of the bugs:

  1. Sometimes it stops loading the kernel and just stucks image

  2. Sometimes it show the errors: image

  3. It can also show either black screen or broken logo screen image

Rarely, it boots successfully and runs the program:

Reproduction steps

  1. Switch boot to emmc or tf-card

  2. Connect the board to power supply

  3. Connect the board to UART-USB

  4. Power-on the board

    • Connect to the board

Can you try using another TF card? It's possible that the image file error was caused by a damaged TF card.
