Post by thread:[PIC] Bootloader for 18f4610?

Anyone have any favorite bootloaders for the 18F4610? I've looked at the TinyBootloader and the TheByteFactory CodeLoader. I'm kinda leading towards the CodeLoader code, which is written in CCS C. Though considerably larger, you just send the hex files to it and they are decoded in the bootloader instead of in the host program. However, the CodeLoader code seems to make calls of several functions that are not included in the package of files. I'm moving it over to Microchip C, so perhaps those function calls are defined in CCS C. Any comments? THANKS! Harold -- FCC Rules Updated Daily at http://www.hallikainen.com

Well I've been using the bootloader provided by microchip, modified it a touch so it would trigger based on the level of a input pin so I don't need to put code to reset the EEPROM in my program. Here's a link if you haven't seen it already... http://microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1824&appnote=en012031 I'm using it w/ a PIC18F4525, but you could probably use it w/ your PIC too Works great for me, but the PC software is only available for Windows On Mon, 28 Mar 2005 10:58:20 -0800 (PST), Harold Hallikainen <spam_OUTharoldTakeThisOuThallikainen.com> wrote: {Quote hidden}> Anyone have any favorite bootloaders for the 18F4610?

Thanks for the quick response! I've also used that bootloader before. It looks like the 18F4610 does not support tblwrt, which this bootloader uses. From the datasheet: Note 1: Although it cannot be used in PIC18F2X1X/4X1X devices in normal operation, the TBLWT instruction is still implemented in the instruction set. Executing the instruction takes two instruction cycles, but effectively results in a NOP. 2: The TBLWT instruction is available only in programming modes and is used during In-Circuit Serial Programming™ (ICSP™). I look forward to any more comments! Thanks!
