[ 10.3985 ] Erasing spi: 0 … [Done]
[ 194.4133 ] Writing partition secondary_gpt with gpt_secondary_3_0.bin [ 16896 bytes ]
180 seconds are spent on erasing SPI,. How can I optimize this burning time？
Is your host PC using USB 3? Or is it using something slower? I don’t think you can change how fast erasing goes, but you can slow it by using a slower USB 2. You can verify during the erase on your host PC with “lsusb -tv”. If the number on the right side is “480M”, then it is only USB 2. If the number is “5000M” (or higher), then it is USB 3. This would only change how fast data transfer is, but it wouldn’t change the actual command to erase if the command is not based on data transfer rate.
