   > Ah I remember we were testing that during initial SD implementation hope 
it wont be too hard to fix! :-P
   
   I hope so too; I would think there should be some way to limit the size of 
the write chunks but I couldn't find one yet. If I spend more time on it I 
might get somewhere :)
   
   > Btw @linguini1 I use https://github.com/apache/nuttx/issues/17303 for 
flashing NuttX to rPI-4B without SD card just over the usb-bootloader and the 
rpiboot on the host side.. maybe that would help evade SD problems just for 
comparison or when needed? :-)
   
   That is useful, but I don't think it will work around this issue. The 
problem is because the EMMC2 hardware can only handle a maximum block size of 
1023 at a time. So I will need to split larger chunks into smaller ones, no 
matter what is connected. I should maybe look into getting one of those 
eventually; it's tiring to swap the SD card every time haha!
