Booting pi 4 from USB with SSD on Jmicron SATA USB adapter

I have a Pi4 4GB version, it boots ok with sd card. I followed the instruction here:

 https://www.tomshardware.com/how-to/boot-raspberry-pi-4-usb

it works with my TDK 32GB usb drive, but it does not work with my SATA to USB3 adapter.

Mine looks like the one in this video


then in this discussion:
https://www.raspberrypi.org/forums/viewtopic.php?t=286835

it talks about the adapter of JMicron, and what to do to make it works.

after all the update of eeprom, and setup the pi config, plug in your ssd, use lsusb to find the ID of your adapter. the number may vary, mine is 152d:0578

pi@raspberrypi:~ $ lsusb Bus 002 Device 002: ID 152d:0579 JMicron Technology Corp. / JMicron USA Technology Corp. Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 1411:1819 Bus 001 Device 002: ID 2109:3431 VIA Labs, Inc. Hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

then do the sd copier stuff, make sure it's a new image on your SSD.

we need to add a line in the cmdline.txt of the boot section. I did this in wondows, shutdown the pi. I took the ssd USB drive and plug in windows, it will show up the boot section(it's FAT format), just use any editor to add this line on top of the file:

usb-storage.quirks=152d:0578:u

make sure the ID is the one you saw in lsusb,remember to leave a blank after these chars.


plug it back to Pi4, remove the SD card, then power it up. the first boot will take few minutes. This time it works, I ran a test on my SSD.

good speed!

Heltec ESP32+OLED+Lora, hardware testing

you can easily find some good boards from china, but most of them lack of accurate document... Hrere is an example; https://hackaday.io/project/26991-esp32-board-wifi-lora-32 the board looks good with lora and a 128x64 OLED, but the IIC and reset connection is important, since pin can be muxing easily, so every board could be different. pinMode(16,OUTPUT);  digitalWrite(16, LOW); // set GPIO16 low to reset OLED  delay(50);  digitalWrite(16, HIGH); // while OLED is running, must set GPIO16 to high  and, if needed, edit your Wire.begin() to Wire.begin(4,15); (4 = SDA 15 SCL)  i tested it with the Adafruit SSD1306 and the Acrobotics SSD1306 Librarys  both work.  Display size is 128x64 There are discussions on these boards on TＴＮ as a LORA node..or maybee single ch gateway? Heltec has a git :  https://github.com/Heltec-Aaron-Lee And there is another copy call TTGO https://de.aliexpress.com/item/TTGO-LORA32-868-915-Mhz-SX1276-ESP32-Oled-display-Bluetooth-WIFI

micro SD card for ESP32, on lolin32 with OLED and heltec 32 lora oled

I have purchased 2 micro SD card holder for my esp project. First I would like to test with heltec esp32 lora oled module. this module uses: sck=05 MISO=19 MOSI=27 SS(lora)=18, then I assigned 21 for sd SS and there is a lib in esp32-arduino, which use SS default at 5 I took the example and use SD.begin(21), but I alway get the error: entry 0x40078a9c Card Mount Failed But I do saw once that it read out the sd card type and volume. Not sure it's the issue of lora sd card swithing, or it just can't work. The other esp32 card I have is an wemos esp32 oled, it did not leave me too much pins, I need to find out how to connect sd to it. But I have wemos D1 mini esp8266 on hand, and connect it as:  * The WeMos Micro SD Shield uses:  * D5, D6, D7, D8, 3V3 and G  *  * The shield uses SPI bus pins:  * D5 = CLK  * D6 = MISO  * D7 = MOSI  * D8 = CS It's not working with the example in the arduino IDE 1.8.5, which marked SD(esp8266), but it w

Install Network Time Protocol(NTP) on BeagleBone with Angstrom linux and set local time zone

Referenced from : http://cwraig.id.au/?p=513 1. Update your Package List opkg update 2. Get the ntp Package opkg install ntp ntpdate Update 2014/07/03 for the latest beaglebone image(2013-06-20) with kernel 3.8.12, after this installation,  system will add to service list, so only need to change time zone 3. Now we need to stop the ntpd service so we can request a manual update /etc/init.d/ntpd stop manual update ntpdate pool.ntp.org type in date, you should see the date is changing to current date and time, but the time zone is not corrected. The time zone info is contained in /etc/localtime , use this to remove it: rm /etc/localtime before link up our time zone, look into /usr/share/zoneinfo folder for your timezone. I did not find taiwan in asia, not plan to use hong_kong, but there is still: /usr/share/zoneinfo/Etc/GMT-8 now we make the link with ln command ln -s /usr/share/zoneinfo/Etc/GMT-8 /etc/localtime now type date again to check, should ha
