bootloader/bootloader.c:102: error 158: overflow in implicit constant conversion

[coleharlow12]

I keep getting this error when I try to use the makefile to compile the source code. I believe this error is coming from SDCC but I am unsure of how to fix it. The code in question is

for (i = 0; i < 255; i++) {

SDCC might be treating 0 and 255 as signed integers. The following gets rid of the error. However, more errors follow.

for (i = 0u; i < 255u; i++) {

same here, how is this supposed to be fixed?
@tridge ?

for now you'll need to download and build an older release of sdcc
