Tiny Multi Bootloader+ / Discussion / General Discussion: 16F-12F TMBL+ Bootloader Generator

Anobium - 2020-09-18

Introduction

I have written a new bootloader generator for 16f and 12Fs. The new bootloader generator is fully automatic in generating a bootloader that is specific to a specific requirement.

This resovle the configuration of the bootloader - is very very simple and very fast.

Users can configure the following:

Frequency

Baud Rate

Startup Delay

Serial Ports - either PPS or AFP

I have, at the moment, limited support to chips with USART. If there is a real need for non-USART chips then I may consider it.

The purpose of the new bootloader generator is establish a new level of quality in terms of the generated bootloader.

How does this work?

The new bootloader generator is wrttien in Great Cow BASIC and the new bootloader generator uses all the intelligence witin Great Cow BASIC to control the 500 chips configurations.

Set produce a HEX is very simple.

Set the chip and frequency - like #chip 16f18855,4

Set the baud rate - like USART_BAUD_RATE 115200

Set the PPS - using PPSTool - so this is very simple

Set the AFP - if needed

Done.

The generated ASM is past automatically via MPASMX to generate the HEX.

Clearly this is a little more complex in the background but we using the power of Great Cow BASIC and Microchip to produce the HEX.

Examples

If you want to try the new HEX please ping me. State the requirements

Frequency

Baud Rate

Startup Delay

Serial Ports - using ether PPS or AFP

Chips - there are probably 100s more

Working on the same for the 18f range.

PING ME for a sample HEX!!

This is an example ASM generated. The example shows the level of integration with Great Cow BASIC.

This is automatically generated with any changes from the default being made in the PICINFO.EXE software. PICINFO validates the config.

LIST p=16F18854, r=DEC #include <P16F18854.inc> __CONFIG _CONFIG1, _CLKOUTEN_OFF & _RSTOSC_HFINT32 & _FEXTOSC_OFF __CONFIG _CONFIG2, _MCLRE_OFF __CONFIG _CONFIG3, _WDTE_OFF __CONFIG _CONFIG4, _LVP_OFF __CONFIG _CONFIG5, _CPD_OFF & _CP_OFF

Memory location are automatically calculated (NOT A SCRIPT) but from the Great Cow BASIC chip definition file. Memory sizes and memory maps are Great Cow BASIC constants.

;Start of the main program

#define BUFFER_SIZE 80 #define BUFFER_LOCATION 0x0020 errorlevel -302, -306 #DEFINE FIRST_ADDRESS 3996 CBLOCK ( 512 - 7 ) __CHECKSUM __I __COUNTER __FLAG __CNT1 __CNT2 __CNT3 ENDC ORG 3996 ORG 4000

Registers and setup already existed in Great Cow BASIC, so the generator simply uses these constants to populate variable calcs and register names.

ENTERBOOTLOADER movlp ( 4096 >> 8 ) -1 bsf FSR0H,0 movlw ( RC1REG & 255 ) movwf FSR0L CONFIGOSCILLATOR movlw 96 banksel OSCCON1 movwf OSCCON1 movlw 6 movwf OSCFRQ

PPS is integrated with the PPSTOOL. To make the setup of PPS easy.

PPSLOCKCONTROL movlw 20 banksel RC6PPS movwf RC6PPS bcf ANSELC,7 movlw 23 banksel RXPPS movwf RXPPS

The same source program supports three different chip architectures

NVMCON1SUPPORT PMCON1SUPPORT EEMCON1SUPPORT

As part of the project I have also updated the TBL+ exe. This is now version 12.4

The new version includes programming the bootloader using PICKitPlus, new support for interbyte transmissions, improved GUI experience.

Enjoy!!

I should share the update to documentation. This shows the configuration. This is very useful to validate the config.

;Start of the main program ;asm showdebug ';CHIPARCHITECTURE = 1 = NV Memory ;asm showdebug ';CHIPARCHITECTURE = 2 = PM Memory ;asm showdebug ';CHIPARCHITECTURE = 4 = EE Memory #DEFINE _CHIPARCHITECTURE .. 1 #DEFINE _IDTYPEPIC ............ 220[DECIMAL] #DEFINE _CHIP ................. 16F19156 #DEFINE _FREQUENCY ............ 32 MHZ #DEFINE _BAUD RATE ............ 115200 #DEFINE _PROGMEM WORDS ........ 16384 #DEFINE _RAM BYTES ............ 2048 #DEFINE _CHIPFAMILY ........... 15 #DEFINE _EEMEMORY BYTES ....... 256 #DEFINE _SAFMEMORY WORDS ...... 128 #DEFINE _HEFMEMORY WORDS ...... 0 #DEFINE _HEFSAFMANAGED WORDS .. 96 #DEFINE _PPS_CHIP ............. YES #DEFINE _PPS_CONFIG_DEFINED ... YES #DEFINE _PPSTOOLPART .......... 16F19156 #DEFINE _TIMERDELAY ........... 1 SECS

This specific config shows - the IDTYPEPIC which relates to the PICCODES.INI, the chip and that the chip IS PPS, the PPS is configured, and the PPS is related to this chip (not another in error), the SAF memory protected (96 bytes). This also shows at the top the memory architecture - this is a type 1 therefore a NV memory chip.

Other parameters include TNBL+ timer delay, Baudrate and other key chip parameters.

There is error checking. An error message will be shown - If PPS setup does not match the selected chip or the SAF/HEF is not availiable but has been specified. Examples follow:

WARNING_PPS_MISMATCH_OR_INCORRECT_PPS_SETTING

This documentation really helps get the bootloader working at the first attempt.

I have now added the following microcontrollers to the automatic generator process.

Target chips: 16f707, 16f720, 16f721, 16f722, 16f722a, 16f723, 16f723a, 16f724, 16f726, 16f727, 16f73, 16f737, 16f74, 16f747, 16f76, 16f767, 16f77, 16f777, 16f87, 16f870, 16f871, 16f873, 16f873a, 16f874, 16f874a, 16f876, 16f876a, 16f877, 16f877a, 16f88, 16f882, 16f883, 16f884, 16f886, 16f887, 16lf707, 16lf720, 16lf721, 16lf722, 16lf722a, 16lf723, 16lf723a, 16lf724, 16lf726, 16lf727, 16lf73, 16lf74, 16lf747, 16lf76, 16lf767, 16lf77, 16lf777, 16lf87, 16lf870, 16lf871, 16lf873, 16lf873a, 16lf874, 16lf874a, 16lf876, 16lf876a, 16lf877, 16lf877a, 16lf88

If this has an 16f part listed about and there is no 16LF part then you can assume it is supprorted.

The following parameters can be changed to meet specific needs:

Frequency
Baud Rate
Startup Delay
Serial Ports via AFP (if available)
Configuration

This is an example report for 16F886

;Start of the main program #DEFINE _TOOLVERSION .......... 1.04 ;asm showdebug ';CHIPARCHITECTURE = 1 = NV Memory ;asm showdebug ';CHIPARCHITECTURE = 2 = PM Memory ;asm showdebug ';CHIPARCHITECTURE = 4 = EE Memory #DEFINE _CHIPARCHITECTURE .. 4 #DEFINE _IDTYPEPIC ............ 170[DECIMAL] #DEFINE _CHIP ................. 16F886 #DEFINE _FREQUENCY ............ 8 MHZ #DEFINE _BAUD RATE ............ 115200 #DEFINE _PROGMEM WORDS ........ 8192 #DEFINE _RAM BYTES ............ 368 #DEFINE _CHIPFAMILY ........... 14 #DEFINE _EEMEMORY BYTES ....... 256 #DEFINE _TIMERDELAY ........... 1 SECS

The tooling generates HEX of less than 100 words.

(My first post on SourceForge) Yer Tiny Bootloader+ is great and the bootloader generator sounds cool. Is the generator code/executable available somewhere?

Thanx

  I can create a bootloader for chips for 'beer money!'. We have updated the generator to create bootloaders for chips that require PICAS.
  
  Send me a Personal message to let me know what chip you need bootloader for.
  
  :-)

Hello

Firstly thanks for sharing your bootloader !

But i'm completly loste with available files, i like to found a bootloader UART for 16F1825 this one seem to be in the compatibility list but the file are missing.

Reading this post you says "PING ME for a sample HEX!!" so is possible to have something ?

Best regards

  Create a new posting with your chip name (so, others can find it). I will then put a bootloader on the new post.

Hi,
This is really awesome work you've put into this. I was looking for a PIC16LF18346 bootloader.

Was wondering if you already have a precompiled version I could try?

Thanks!

  Thank you.
  
  See the PDF. What needs to be changed?
  
  So, you are aware I have re-written this is Great Cow BASIC and I still plan to web enable this to make this automated.
  
  Let me know what changes are needed. Please ignore the config as you can edit at your end with ease.

    Thanks for the quick reply! The only change I can see is the part is a LF version. I think I can test it out with all the other settings.
    
    Very interested in the web enable. Will this be a website, or though an application?
    
    Thanks again

      Great. The LF is no different.
      
      Send me a PM or to my email (see https://www.pickitplus.co.uk/Typesetter/index.php/About-Us).
      
      I am thinking web server. I may get time to work on it early next year.

Hi Anobium,

Have you written any bootloader support for the 18F series? Specifically the 18F16Q40?
Thanks!

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
- Anobium - 2023-03-19
  
  Maybe later this week.
  
  I am truly working on this with Microchip. The program in terms of the source is complete by for the Q10 I cannot use MPASM and therefore I must use PIC-AS ( the latest tool for these chips).
  
  I have an engineer allocated to help me this week and as I write this I writing up the technical specification of TBL+ for the engineer.
  
  So, check back next week.
