Compile the code and look at the disassembly running in a M16C/R8C simulation session. 2008-11-15T20:30:09Z Comment http://www.renesasrulz.com/forum/r8c-tiny/574884879/947701384/view Easy way to check: x = sizeof(long long int); Now, examine x using a simulator/debugger or display it on the terminal. 2008-11-15T09:55:55Z Comment http://www.renesasrulz.com/forum/r8c-tiny/574884879/747099506/view Hi,   I am adding an encryption functionality to an R5F21237 on the CanD demo board.  This encryption uses a 64 bit key, which is XORed and ... 2008-11-14T19:04:43Z Comment http://www.renesasrulz.com/forum/r8c-tiny/670716351/712242519/view This is a tricky one. Maybe there's a pullup resistor with a cold solder joint? If the boards are made exactly the same, they should work exactly the same. 2008-11-10T13:18:14Z Comment http://www.renesasrulz.com/forum/r8c-tiny/670716351/658042076/view I built a circuit using r8c/1b but i have connection problems with E8a. The programmer sometimes connect, sometimes gives timeout error. what can the problem ... 2008-11-09T11:51:23Z Comment http://www.renesasrulz.com/forum/r8c-tiny/654182111/976714986/view This problem always trouble the new user of HEW, we don't know why Renesas won't to correct it until now. Here I would like to suggest Renesas that the ... 2008-11-07T05:28:21Z Comment http://www.renesasrulz.com/forum/r8c-tiny/251832285/326397123/view Regarding undocumented RAM: The manuals say that SFRs end at 0x2ff. Range 0x300..0x3ff is listed as empty. In fact, this range contains RAM used by Renesas ... 2008-11-05T22:06:01Z Comment http://www.renesasrulz.com/forum/r8c-tiny/654182111/393164968/view Right, the improper stack init causes the program to crash during first stack read (usually first function return) and has nothing to do with program loading. ... 2008-11-05T17:41:32Z Comment http://www.renesasrulz.com/forum/r8c-tiny/251832285/125028115/view You are right. The manual says minimum 4.7k pull-up. We use 10k pull-up on our hardware and that works fine stand alone and with E8a. 2008-11-05T14:41:36Z Comment http://www.renesasrulz.com/forum/r8c-tiny/251832285/427729084/view FrankL: That would make sense, but: - nothing is said in Hardware Manual about -RESET pin internal pullup, - FAQ says it's necessary to guarantee 0.8 ... 2008-11-05T12:25:58Z Comment http://www.renesasrulz.com/forum/r8c-tiny/654182111/810781089/view Why should a bug in assembly startup cause an error message on software download to E8a? At the time of download this is not executed... . 2008-11-05T11:20:31Z Comment http://www.renesasrulz.com/forum/r8c-tiny/654182111/583522271/view Yes, there is a well-known bug in assembly startup which was corrected in 5.43. The problems lies in incorrect order of first instructions after reset, ... 2008-11-05T10:10:17Z Comment http://www.renesasrulz.com/forum/r8c-tiny/654182111/771786716/view You have a problem with your application overlapping the E8a firmware. Check which memory you use in your map file, and check the settings for firmware ... 2008-11-05T07:47:43Z Comment http://www.renesasrulz.com/forum/r8c-tiny/251832285/16420847/view No, this no resistor in the FAQ means leave it open. E8a has internally a pull-up on Reset, so you don't need it in the target. If you connect Reset directly ... 2008-11-05T07:44:55Z Comment http://www.renesasrulz.com/forum/r8c-tiny/654182111/676690891/view Hi together, I am new on the R8C controller.
