[SC64][BUG] Cannot upload to subfolder on SD card

[MartinMajewski]

Is your issue really a bug?

• I understand the difference between flashcart firmware, N64FlashcartMenu and sc64deployer PC app.
• I found a bug in FPGA HDL (/fw/rtl)
• I found a bug in MCU app (/sw/controller)
• I found a bug in N64 bootloader (/sw/bootloader)
• I found a bug in PC app (/sw/deployer)
• I found a bug in initial programming script (/sw/tools/primer.py)
• I found an error in documentation (/docs)
• I found an issue elsewhere

Firmware version

v2.20.2

Describe the bug

I can upload files to the root directory but not to any subfolders. My roms are in /roms, and my homebrew stuff is in /dev.

I'm working on a Mac with MacOS 15.2 (24C101), and the sc64deployer works fine except for the upload functionality.
I formatted the SD card with extFS first, but after running the SD card in Summercart64 once, I had permission issues with the subfolders on my Mac. Then, I formatted it with Fat32 (which has no advanced permissions structure), but I got the same error (see the logs section) during the upload.

Moreover, I created the roms folder on my Mac and the dev folder with the deployer app; however, the same behavior was observed.

Output logs from sc64deployer info

➜  projects git:(dev) sc64deployer sd upload hello.z64 /dev 
FatFs error: Access denied due to prohibited access or directory full

sc64deployer sd upload hello.z64 /dev

Instead try:

sc64deployer sd upload hello.z64 /dev/hello.z64

This has worked for me on my Mac to upload files to a particular directory. Hope this helps. Thanks!

Note: I'm not sure if this will work correctly if there's already a file with the same name in that directory. I've always removed files (rm) before uploading like a new version with the same name.

Note 2: I'm also using FAT32. I formatted the SD card and created the original directory structure originally on my Mac.

Note 3: Also note that it is possible to upload files from a directory that is not the working directory as long as you follow normal *nix commandline rules, escaping spaces and/or using quotation marks, etc.

Example:

sc64deployer sd upload /Users/bob/Desktop/hello.z64 /dev/hello.z64

@MartinMajewski The issue is with very basic implementation of the upload/download commands in the sc64deployer. Currently these command require you to specify the complete destination path with file name. When you type sc64deployer sd upload hello.z64 /dev, the program tries to create the file /dev on the SD card. Problem is that this is an existing directory and FatFs correctly refuses to overwrite directory entry with a file.

Leaving this issue open as these commands need to be improved to behave more like cp commands in UNIX systems.
