As I recall, 4 flashes means the kernel is not loading.radnor302 wrote: ↑Tue Feb 26, 2019 10:59 pmThank you the reply.
Still no joy..... Did every step.
Once I did the FAT32 with bootcode.bin I had the rainbow screen.
Then I added the file timeout (empty file) to the FAT32 partition.
Now it sends me a "B" in morse code (3 short flashes followed by a long from the green led next to the power led)
That is not helpful. Exactly what power supply is it?
It would be nice if it was really that simple, but for a lot of people it's not. The Raspberry Pi boot-loader is not compatible with all USB mass storage devices, resulting in problems for some people. Symptoms are either not booting at all, or cold boot works but reboot does not. And people who want to boot from a hard drive can have additional problems due to their power consumption and long spin-up times.kingbily wrote: ↑Mon Mar 04, 2019 5:23 pmBoot your Raspberry Pi from the USB mass storage device.
After five to ten seconds, the Raspberry Pi should begin booting and show the rainbow splash screen on an attached display.
Note that if the USB boot bit is set, you do not need to insert an SD card into the Raspberry Pi for USB boot to work.
The later version Pi2B v1.2 has the same SoC as the Pi 3B, so I believe it supports no-SD card USB boot. The earlier version 1.1 would need a FAT32 SD card with the bootcode.bin file on it (you can USB boot any consumer Pi model that way, even the Pi Zero).
And what USB-SATA adapter are you using?Yeahthisisausername wrote: ↑Fri Mar 22, 2019 6:31 pm$30-ish, 120 GB Kingston A400 SSD works flawlessly on my 3B+. Boots and reboots just fine. Now you know.
Use the SD Card Copier utility included with desktop versions of Raspbian (with New Partition UUIDs checked)..
No it will not.sushant_ocv wrote: ↑Thu May 30, 2019 6:12 amHey mate,
Will booting from my external HDD minimize file system corruption issues which right now coming through SD Disk when power is gone?
Please provide your views.
Sorry to dissappoint, but you are not. Probably not even in the first hundred, it's much asked in the Pi4 threads (actually OT for this thread).HelenMcCall wrote: ↑Fri Jul 05, 2019 10:13 pmHello. Looks like I'm the first to ask this question:

You're only about TWELVE days late asking that.HelenMcCall wrote: ↑Fri Jul 05, 2019 10:13 pmHello. Looks like I'm the first to ask this question:

Woah. That is the most awesome thing ive seen all day. Would this work with a pi 26by9 wrote: ↑Tue Jul 26, 2016 2:24 pmPlease reaBy default this is SD card boot followed by USBaudacity temp mail origin device boot. Subsequently, the boot ROM checks to see if program_gpio_bootmode OTP bit is set, if it is then it reads either GPIOs 22-26 or 39-43 (depending on the value of program_gpio_bootpos) and uses those bits to disable boot modes. This means it is possible to use a hardware switch to switch between different boot modes if there are more than one available.So you can control which boot devices to check via GPIOs, or only enable certain modes in the OTP in the first place.If there is no SD card inserted the SD boot mode takes five seconds to fail. To reduce this and fall back to USB more quickly, you can either insert an SD card with nothing on it or use the program_gpio_bootmode OTP to only enable USB.
I don't know whether just having USB mass storage enabled is faster than, but at least it would avoid some of the timeouts.
