![]() ![]() Thank you to /blog/enable-or-disable-folder-options-in-windows/ for sending me in the right direction. unlock the write protect tab etc, change the registry keys etc.), it's simply a Windows 7 or Windows 10 setting. YOU CAN THANK ME LATER ! - The Solution is hidden within gpedit.mscĪfter sifting through all the frankly useless 'help' out there ( e.g. If it says Disk Write Protected, then check Then remove the "Read Only" check by the box and try toĭelete or add files then. You have existing files on the SD card, insert it, right click, select Sometimes it takes several tries, but it will work with patience. The manual says to insert a blank memory card, turn the camera on and off, remove the card, and there should be a PC executable file, timetool.exe written. ![]() The plastic tab is closet to the side you insert in the device you are I dont have opened explorer (booted and started USB Image Tool). 'Could not write to the USB device (code:5) Please close all open explorer windows for this device. Double check that you did not cover the connection edge, and in order to backup and restore an SD card (32GB) I use 'USB Image Tool' on my Windows 10 computer. If you get the same error again after applying the tape, add a second Reader, format it, read and write files to your desire. The brass connector on the opposite side. Be very precise in placing the tape over the notch, but not over Place a piece of tape, masking, electrical, sometimes transparent will Try applying scotch tape to the card and see, if this works: I also was able to transfer files to and from TERATERM and you can type ^Z on teraterm and it ends the transfer.Since ejecting the SD card and reinserting it works, I suppose that it's your built-in card reader having issues with SD card's write-protect switch. I do get a LOW memory warning when compiling 18,560 of storage space(60), 1,550 of dynamic memory(75) I'm stumped. The attached code creates the file on the SD card 'TEST.TXT' but will not write to it. But can always use LOAD and UNLOAD to send hex files, which includes the checksum in each line. The SD card works fine using the examples. Of course, the characters are truncated to 7 bits and I added this in the same way as the CON, so can't send binary files. On the receiving machine PIP TEST.TXT=RDR:Īnd it transferred the file! No need to patch xmodem, this is CP/M running out of the box. On the sending machine PIP PUN:=LOREM.TXT,EOF: (sends a ^Z at the end) In general, you communicate with the SD card via commands (see 7.3.1.1 Command format in the specifications) which the SPI master sends to the SD card (SPI slave). Added in Serial1 and linked it to the PUN and RDR CP/M calls. (or directly, but I zapped some other boards a while back inadvertently linking 3V and 5V boards, so prefer the robustness of RS232). The ESP32 is cheap enough you can flash a couple of boards, and then link them with cheap RS3232 to TTL modules.

Meanwhile, tiny little hack I have wanted to do for years - file tranfers between CP/M machines using PIP. This weatherproof, rugged trail camera is designed to record still images or movie. Quick perusal through the code, I dunno, 20 to 50 lines need changing.ĭeep inside the code thinking about how to incorporate the working ESP32 SD code. And then there are slight differences in the way functions are called, eg in runCPM to append a fileį = SD.open((char *)filename, O_WRITE | O_APPEND) And there are two SD.h files that are different, so need to tell the compiler which one is being used (more ifdefs). There are some syntax changes, for instance, no need to declare which pins are which as these are fixed. If the first line says 'Current Read-only State: Yes', and the second line says 'Read-only : No' that means that something is wrong with the physical mechanism that tells your computer if the card is locked or not. what would it take to port this code into the RunCPM? Lots of #ifdefs I suspect. If the lock switch is in the write position and you can confirm that the SD card works in other devices, check the drive in diskpart. Ok, on the arduino IDE once ESP 32 is installed, File/Examples/ESP32 examples,/SD(esp32)/SD_Test., this appears to be the official SD code for the ESP32, and indeed it works fine for every SD card I can find. Works with sandisk and kingston, not with no-name sd cards. ![]() Simple test for writes - start MBASIC, write a one line program and then save it. More experiments August 2nd regarding the SD card and ESP32. ![]()
