Title: certainly a beginner question, sub ram_variable not possible Post by: sonflasch on November 07, 2019, 12:39:28 PM Hello @ all
I'm trying to change a subtraction in 551k file (adress 87A69E) mov r4, plsol_w sub r4,plgru_w ->>> 22 F4 66 A6 change in mov r4, plsol_w sub r4, pu_w ->> that would have to ->> 22 F4 8C 0A I look for where pu_w is used fits 8C 0A is right, but it does not work. I'm looking for a subtraction with pu_w .. there are too 8C 0A. I do that in 551f where pu_w is also in the range of 382xxx it works fine. can explain to me one why that does not work at 551k. I try to explain it but I miss the knowledge? or can someone give me a solution many thanks Title: Re: certainly a beginner question, sub ram_variable not possible Post by: fknbrkn on November 07, 2019, 06:35:54 PM Pu_w @384A8C Short adressing cannot be applied to that offset Use extp #0E1h, #1 D7 40 E1 00 sub r4, pu_w 42 F5 8C 0A or exts #38h etc Title: Re: certainly a beginner question, sub ram_variable not possible Post by: sonflasch on November 07, 2019, 08:56:37 PM thanks... ;D ;D
