Tiny Multi Bootloader+ / Discussion / General Discussion: dsPIC30 Bootloader

Dan - 2014-06-14

Hi,All

I was successful in writing flash of dsPIC30.

I verified the Config and EEPROM current.

Contributions Once I have completed.

I think to become a template for 24/24H/dsPIC33.

Hi,All

dsPIC30 corresponding version was completed.

I attach the host program.

and ds30F3012's firmware.

and ds33FJ128GP202's firmware.

(If you create the firmware, also corresponds to the writing of the PIC24.)

My Change: //$nn

Details of the changes described in the ReadMe.txt

Hi,All

I was able to operate also confirmed PIC24HJ12GP202.

Corresponding to the D type is almost complete.

Hi,All

Distinction of the E-type and D-type.

Relationship with the E-type and D-type is similar to the relationship of PIC18J and PIC18.

"Frash Config Words" does not exist in the D-type.

[Device corresponding to the D-type]
dsPIC30F
PIC24F
PIC24FV
PIC24HJ
PIC24E(Partial)
dsPIC33F(Partial)
dsPIC33E(Partial)

[Device corresponding to the E-type]
PIC24FJ
PIC24E(Partial)

Hi,All

Modified the host program, I also support E-Type.

I attach the firmware and modified version host program.

The host program the previous presentation, reset by the RTS was disabled.
(Reset by the DTR is enabled.)

I was back to the original specification in a modified version of this.

Hi,All

Because I can cope with PIC device of all the Tiny AVR/PIC Bootloader+,
for data transfer format, I will summarize here.

Action command does not exist in Tiny AVR/PIC Bootloader+.
Rather than a command from the host side, perform firmware is necessary to erase flash memory.

1.The type of data transfer

There are three data to be transferred from Tiny AVR/PIC Bootloader+ host.

①Flash Data
②EEPROM Data
③Config Data (24-bit PIC and PIC18F)

Represents the character of one byte [] below.

2.Data format of 14-bit PIC (PIC10F/12F/16F), "B"-Family

①Flash transfer format:

[AddressH] Start address of the flash page to override the data. (upper)
[AddressL] Start address of the flash page to override the data. (lower)
[2*N] Number of transfers of data as described in piccode.ini. (byte notation)
[DataL/H(n)] Rewrite data (2*N)bytes.
[SUM] Checksum.

Hello Dan!

Thanks a lot for the new "D" and "E" families support in TinyBootloader+, the new firmwares and all the updates you made! You're great!!! I hope we'll meet one day :-)

So, by now I'm gathering everything from your posts and I'll post a v0.9.0 with all your addons.

Best regards,
Edorul

Steven Nelson - 2016-10-03

I downloaded the code looking for the (partial) support of the dsPIC33E chips, and under the Type D folder, there are no files! Did these get dropped somewhere?
I've been trying to modify MicroChip's dsPIC33E bootloaders, but have had little success--was hoping that Tiny Multi Bootloader+ might be the answer...

Hi,Nelson
Please look for the following fofolders.

Tiny_Avr-Pic_Bootloader+ (v0.9.0)
Tiny Multi Bootloader+ (v0.10.0)

Best regards,
Dan

Hi Dan, i have been trying for months on increasing the TinyBootloader size from 100words to about 200words for PIC18, what do i need to change in the code and PC Software?

  Why? Same question.
  
  If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

Dan - 2018-05-24

Hi,

Firmware size can not be freely selected.
If the erase/write unit is 16 words
84, 100, 116, 132 ...
If the erase/write unit is 32 words
100, 132, 164, ....
If the erase/write unit is 64 words
132, 196, .........

Please make it to be N x U + 4 for erase/write unit U. (N = 1, 2, 3, ....)

2.Change piccodes.ini
Even if the corresponding device already exists, assign another number.
The following is an example of PIC10F322

; PIC10 family
; example: PIC10F322 Flash: 512 words = 200h; 200h*2 = 400h
;-----------
$11, B, 10F 322 (100W), $400, $000, default, 32,
$12, B, 10F 322 (84W), $400, $000, 168, 32,

Thank you Dan, That information was very helpful, so i can adjust the firmware size from the piccodes.ini only or do i need to change any other thing in the PC software?

i really appreciate your reply.

Hello Dan, please write an example for PIC16F877 to be firmware size to about 132 words

Hello Dan, Thank You for your replies, but when i inserted the example you gave to me and try to write into the MCU, i still get this error messages "Error: hex file too large, writing bootloader firmware!!!
* Error: problem in writing MCU memory!!!"

Hi

Error: hex file too large, writing bootloader firmware!!!
* Error: problem in writing MCU memory!!!"

Is the upper limit of HEX file 0x1F7B or less?

Does this work?

I still get the same error messages, i found out that your code is still running on 20MHz even when the xtal is 8MHz

xtal EQU 8000000 ; you may also want to change: _HS_OSC _XT_OSC

Is your target 16F, 18F?

Code made with 18f can not flow to 16F.

I already changed the code back on 16F but its still conplaining about the same error,

Initially the PC Software couldn't detect the MCU, then i detected this in the code

MainLoop:
movlw 'B'

but now it was able to detect the MCU when i changed it back to

MainLoop:
movlw 'K'

the problem is that it still conplain of memory even when `#define first_address max_flash-132 ; 132 word in size`

i really appreciate your replies
