Just got back on-line. 512GB and 1TB = very surreal. When I ordered the 512GB samsung was kind of nervous but worked, was nervous about the 1TB card.Originally Posted by PaulStoffregen
Just ordered the pair that of 32GB that was posted - should get on Friday.
Again played a little more and did the changes for Serial2-6 have not done the LPUART (Serial6 on T3.6). Ran simple test code USBToSerial to make sure I could at least ring back each of the serial ports.
Again would be better to get some more testing, but wondering if this is something we would like in PR?Code:/* USB to Serial - Teensy becomes a USB to Serial converter http://dorkbotpdx.org/blog/paul/teensy_as_benito_at_57600_baud You must select Serial from the "Tools > USB Type" menu This example code is in the public domain. */ // set this to the hardware serial port you wish to use #define HWSERIAL Serial5 uint8_t tx_buffer[128]; uint8_t rx_buffer[128]; unsigned long baud = 19200; const int reset_pin = 4; const int led_pin = 13; // 13 = Teensy 3.X & LC // 11 = Teensy 2.0 // 6 = Teensy++ 2.0 void setup() { pinMode(led_pin, OUTPUT); digitalWrite(led_pin, LOW); digitalWrite(reset_pin, HIGH); pinMode(reset_pin, OUTPUT); Serial.begin(baud); // USB, communication to PC or Mac HWSERIAL.begin(baud); // communication to hardware serial HWSERIAL.addMemoryForRead(rx_buffer, sizeof(rx_buffer)); HWSERIAL.addMemoryForWrite(tx_buffer, sizeof(tx_buffer)); } long led_on_time=0; byte buffer[80]; unsigned char prev_dtr = 0; void loop() { unsigned char dtr; int rd, wr, n; // check if any data has arrived on the USB virtual serial port rd = Serial.available(); if (rd > 0) { // check if the hardware serial port is ready to transmit wr = HWSERIAL.availableForWrite(); Serial.printf("(%d : %d)\n", rd, wr); if (wr > 0) { // compute how much data to move, the smallest // of rd, wr and the buffer size if (rd > wr) rd = wr; if (rd > 80) rd = 80; // read data from the USB port n = Serial.readBytes((char *)buffer, rd); // write it to the hardware serial port HWSERIAL.write(buffer, n); // turn on the LED to indicate activity digitalWrite(led_pin, HIGH); led_on_time = millis(); } } // check if any data has arrived on the hardware serial port rd = HWSERIAL.available(); if (rd > 0) { // check if the USB virtual serial port is ready to transmit wr = Serial.availableForWrite(); if (wr > 0) { // compute how much data to move, the smallest // of rd, wr and the buffer size if (rd > wr) rd = wr; if (rd > 80) rd = 80; // read data from the hardware serial port n = HWSERIAL.readBytes((char *)buffer, rd); // write it to the USB port Serial.write(buffer, n); // turn on the LED to indicate activity digitalWrite(led_pin, HIGH); led_on_time = millis(); } } // check if the USB virtual serial port has raised DTR dtr = Serial.dtr(); if (dtr && !prev_dtr) { digitalWrite(reset_pin, LOW); delayMicroseconds(250); digitalWrite(reset_pin, HIGH); } prev_dtr = dtr; // if the LED has been left on without more activity, turn it off if (millis() - led_on_time > 3) { digitalWrite(led_pin, LOW); } // check if the USB virtual serial wants a new baud rate if (Serial.baud() != baud) { baud = Serial.baud(); if (baud == 57600) { // This ugly hack is necessary for talking // to the arduino bootloader, which actually // communicates at 58824 baud (+2.1% error). // Teensyduino will configure the UART for // the closest baud rate, which is 57143 // baud (-0.8% error). Serial communication // can tolerate about 2.5% error, so the // combined error is too large. Simply // setting the baud rate to the same as // arduino's actual baud rate works. HWSERIAL.begin(58824); } else { HWSERIAL.begin(baud); } } }
Some of the subtle things to test out include things like the watermarks and when to assert the RTS.
Used 512GB without issues with T3.6 (so far) and have to transition to 1TB cards soon (T4.1 with multiple SPI microSD).
Together with the normal cards, I ordered one of the cheap no-name 512GB cards with the assumption it's really just 32 or 64 and would likely get corrupted if more is written. Last night I copied 390GB of MP3 files onto that card. Right now I'm listening to one of the first group copied. I'm still expecting the capacity claim to be a lie, but the fact that it's working at all seems pretty amazing!
Just tested both chips on the T4.2 on the BuiltinSDCard and on the T3.2 with an external Card reader, both worked no problem. Also tested with an external card reader on a T4.0.

Thanks @mjs513,
Will retest the one I have, maybe with some other external SD reader. Like maybe one on an Adafruit display board... The one I was using was a sparkfun one with level shifters, which should work for 3.3 or 5v, but who knows, maybe something maybe sensitive on these type cards with signals coming and going through TXB104 shifters.
Note: I just ordered one of each also... Although for the one that supposedly matches the one I already had (cheaper one), I upped it to the 64mb version.
Hi @Paul and @mjs513
Sort of interesting that I retried the one on the Sparkfun board and it failed again. Several other MicroSds worked. This is a T4
I then hooked up Adafruit ST7789 display to second T4 and hooked up the SDCS pin from the display to pin 4... And the Samsung EVO SDHC worked... Will be interesting to see when the two other arrive.
Hi all! The 1.54b4 build worked great for us. We used it for the Pigweed remoticon workshop today: https://hackaday.io/project/175167-r...igweed-a-whirl
Step by step guide is here: https://pigweed.googlesource.com/pig...shop/README.md
Thank you for all the hard work getting 1.54 out the door! I'll update to stable when y'all release it.
A question about the SD wrapper for SDFat: Will I be able to use the sync() function if I use only SD.h? I've found that the sync() function is very helpful in long data logging sessions for two reasons: 1: it updates the directory so you can minimize data loss if the logger loses power in the middle of a logging session, 2: calling sync() puts the SD card into idle mode which significantly reduces power consumption. https://forum.pjrc.com/threads/59526...ync()-in-EXFat
Use SD.flush(), which is calling sdfat's sync().
Or use SD.sdfs.sync();
SD.sdfs is declared public , so you can use sdfat functions directly.
Quick update: I went ahead and ordered a couple more of the Samsung EVO Select cards and will try them out again. In particular will be interesting to see if the two new ones act different than the ones I ordered maybe two years ago in the top of the picture. The 3 32gb ones are marked in small letters under the EVO Select as HC... The 64 is marked XC
Again no idea how different they are both will write up to 20mb/s the HC one is marked Read up to 95 and the XC up to 100MB....
Quick update: The Sparkfun adapter appears to be able to work with both of these... So for the heck of it, I am right now using SDFormatter on one of the old ones to completely erase and overwrite it and will see if it likes it then... It is taking awhile to do the full overwrite.
Ok I did a complete low level reformat of one of the older ones, which created one Fat32 drive... I tried it again on the Sparkfun SPI adapter Pin 4 and it failed to initialize again. Tried it on different T4 with Adafruit display and SDCard connected again on Pin 4 and it reads the SD... Maybe I should go ping this to Sparkfun!
Edit: Emailed Sparkfun... Also including photo of back showing the two old ones and the new one.
The one on left is new one.. Same top number but different second number... Probably some hardware revision happened.

I don't have any of the EVO Selects, but I have been doing my own playing and bench testing of cards on a 4.1, 1-54B4, with the Built in reader and FIFO_SDIO. All of these cards have worked. I can even read two "bricked" cards that nothing else seems to want to. (marked with X in bottom of pic. Most of the cards write in the 12-18MB/s range, and almost all of them will read around 22.8MB/s. The old Samsung pro writes faster than the newer one. (20 vs 17 MB/s). All cards tested were empty and freshly formatted with SDCardFormmatterV5.
These are my fastest cards. these will all write roughly 20.8MB/s, and read at roughly 22.8MB/s. The most consistent between all the tests has been the SanDiskExtreme 16GB U3. The Fastest is one of my older 32GB EVO cards that writes @ 21.3 and reads @ 23.0

These numbers suggest we are using High Speed Mode (25 MB/s) 50mhz-4bit clocking and not UHS clocking. Wonder if the hardware can handle at least the slower 100Mhz UHS clock and 50MB/s. I won't beg for the 208MHz rate of 104MB/s...
LB
The CPU Spec sheet looks promising for even the higher UHS-1 spec
I've dug through the code and don't see any support for UHS-1. Would probably take a bit of work to do more than a hack job of it. Probably be a good "Feature Request'
Last edited by LitterBug; 11-12-2020 at 02:45 AM.
From what I've read, to do UHS-1, you would need to drop the voltage from 3.3v to 1.8 on each of the 4 data pins and VDD. UHS-2 requires 0.4v and it has double the pins:
From what I'm reading in the CPU specs and manual, That can be done using the SD/SDIO interfaces. Data sheets are here https://www.pjrc.com/teensy/datasheets.html
High level DataSheet: https://www.pjrc.com/teensy/IMXRT1060CEC_rev0_1.pdf
Deep dive Manual: https://www.pjrc.com/teensy/IMXRT1060RM_rev2.pdf
From page 1376 of the processor manual
EDIT: So full UHS-1 support "should" be possible on the T4.0 and T4.1 as long as the SD card is connected to one of the two SDIO interfaces.Code:24.3 eMMC/eSD/SDIO This chip has two Ultra Secured Digital Host Controller (uSDHC) modules for SD/ eMMC interface. It provides the interface between the host system and the SD/ SDIO/MMC cards. The key features include: • Support SD/SDIO standard, up to version 3.0 • Support MMC standard, up to version 4.5 • Support 3.3V and 1.8V operation, but do not support 1.2V operation. • Supports 1-bit / 4-bit SD and SDIO modes, 1-bit / 4-bit / 8-bit MMC modes • Up to 800 Mbps of data transfer for SDIO cards using 4 parallel data lines in SDR mode • Up to 400 Mbps of data transfer for SDIO card using 4 parallel data lines in DDR mode • Up to 800 Mbps of data transfer for SDXC cards using 4 parallel data lines in SDR mode • Up to 400 Mbps of data transfer for SDXC card using 4 parallel data lines in DDR mode • Up to 1600 Mbps of data transfer for MMC cards using 8 parallel data lines in SDR mode • Up to 800 Mbps of data transfer for MMC cards using 8 parallel data lines in DDR mode eMMC/eSD/SDIO i.MX RT1060 Processor Reference Manual, Rev. 2, 12/2019 1376 NXP Semiconductor
EDIT2: There is also a whole section on setting up SD/SDIO boot with UHS-1 support....
EDIT3: On the T4.0, you need to use the SD Card (4 bit SDIO) flats on the bottom of the board and an SD card Connector/module with NO level converters.

Cool, thanks for the update.
New TeamGroup 256 GB SD card. From NewEgg : newegg.com/team-128gb-microsdxc
SD\cardinfo.ino gives:

That worked and above bench.ino gave similar results
Is there any chance of making the text entry box and "Send" button at the bottom of the Serial Plotter actually send data to the Teensy? The plotter is occasionally useful when I want to view an ADC input waveform without having to send the data to the PC and using a separate plotting program. It would be nice to be able to start and stop the Teensy output with command characters sent from the plotter instead of having to switch back to the Serial Monitor.
Is this something outside the control of PJRC, or just a low-priority task?
I think I just answered my own question. Recalling the difficulties with double-spaced cut and pasted Serial Monitor output that disappeared when you choose the port from "serial ports" instead of "Teensy Ports", I switched to the "Serial Port" and lo and behold, text from the text box gets sent to the Teensy!
Good find that IDE SerMon Serial does that. Was going to suggest use TyCommander with DualSerial - let IDE Teensy SerMon OWN and do plotting and then the 2nd Serial in TyComm would allow command and also any debug spew.
Here is my latest attempt to fix the double spaced lines on copy to clipboard from the serial monitor on Windows.
Extract this zip file and copy teensy_serialmon.exe to {Arduino}/hardware/tools, replacing the existing file. Windows probably won't let you replace it if the serial monitor is open. The default Arduino location is C:\Program Files (x86)\Arduino.
I ran a quick test here on Windows 10 where it seems to work. Does this solve the double spaced lines on your Windows machine?
@Paul - that works here on Windows 10:
<EDIT> :: This is NOT new behavior - just put back another copy of that file from another 1.54 beta install - and it has the same ODD behaviorCode:Blink again - w/println - before bare println Blink again - w/println - after bare println - end loop. Blink again - w/println - before bare println Blink again - w/println - after bare println - end loop. Blink again - w/println - before bare println Blink again - w/println - after bare println - end loop.
Note: Text select to copy does odd shift of selected text - rather than inverse text color on highlight and stay steady - some lines toggle inverted text color to not visible?
Movie too big - here are three frames ...
@Paul
Seems to work for me here as well. This is a direct copy past from the serial monitor:
