AT89S51 and AT89S52 support for avrdude

[orbanp]

Hello Everyone,

I am new here, so please advise if this is the wrong place to ask the following question.

I am trying to program an AT89S52 chip. I am using avrdude 6.3 and an ebay programmer which is a version of the usbasp programmer. The OS is Kubuntu 20.04 LTS. I am getting the following error message:

$ avrdude -p usbasp -c 5082 -U flash:r:"test.bin":r
avrdude: error at /etc/avrdude.conf:336: programmer type must be written as "id_type"
avrdude: error reading system wide configuration file "/etc/avrdude.conf"

I updated the configuration file that has an entry for the AT89S52 chip, the programmer description is the same that came with the installation. The suggestion that the programmer type should be written in the configuration file with double quotes did not make any difference.

Previously I installed avrdude 7.0 and got the same error. avrdude 6.3 came from the Software Center of the OS.

Any help would be appreciated! Thanks, Peter

I agree with @llinjupt: this is probably nothing AVRDUDE can do about it if the programmer cannot cope with different reset polarity. I suggest closing the issue again.

[mcuee]

Okay, close for now.

[dioannidis]

@mcuee, @llinjupt

The AT89S51 and AT89S52 ICs just arrived :) . Do I need a patched avrdude and conf file or the version from here https://github.com/mcuee/avrdude/releases/tag/v7.1 supports them ?

I'll try to find time next week to test the llinjupt's code and if all is ok then I'll release the 1.11 version .

@dioannidis

I think the idea is not to patch avrdude, but rather patch usbasp FW.

You can use the latest github action mingw-64 build of avrdude main. https://github.com/avrdudes/avrdude/suites/12376320894/artifacts/657514449

[mcuee]

@dioannidis

You can also use my mingw64 build if you prefer. https://github.com/mcuee/avrdude/releases/tag/snapshot_21Apr2023

[dioannidis]

@mcuee

I'll try both ;) ... Thx !

[dioannidis]

@mcuee

Both avrdude mingw64 builds ( yours and avrdude main ) are working fine with the composite firmware ! Thx !

Wondeful.

I will try your modified FW once I get the AT89S52 chip.

[dioannidis]

@llinjupt

@mcuee IMHO, if the programmer doesn't support setting reset polarity, that's impossible to do so. And there are more other strange chips like S2051/AT89S8252/AT89S8253 that behave pretty differently,

< snip >

Fortunately for the USBasp improved firmware to support the AT89S51/2 ICs only the following lines has to be added to ispEnterProgrammingMode() :

           ...
           ...

            /* AT89* Probe */

            ISP_OUT |= (1 << ISP_RST);      /* RST high */
            clockWait(5);                   /* 1.6 ms */

            spiTx(0xAC);
            spiTx(0x53);
            spiTx(0);
            check = spiTx(0);

            if (check == 0x69) 
                return 0;

        } while (--tries);

       ...
       ...

I will try your modified FW once I get the AT89S52 chip.

As I don't use MCS-51 MCUs, I adapted a basic blink assembly program and used the Microchip's c51asm assembler to produce a 27 bytes binary .

Please if it's possible test it with a bigger binary to see if there is a problem .

[dioannidis]

@mcuee

I will try your modified FW once I get the AT89S52 chip.

That file will be deleted . Please use the firmware binaries from the 1.11 pre release from today !

I re uploaded them, because they were corrupted :( See Corrupted firmware binaries in 1.11 pre Release assets

@dioannidis

Thanks. I just got AT89S51 chip. The first test shows it works well.

Please give the FW from @dioannidis a try. It seems to work pretty well. I am using latest avrdude git main (built using MSYS2 mingw64).

No issues with AT89S52 as well.

Sorry for the late reply, I was away travelling. Also thanks for the continuing efforts regarding AT89S52 programming!

Writing the AT89S52 chip is working now, however, reading back the code from the chip I get something different! I updated my usbasp programmer with the "usbasp improved" firmware from dioannidis. I used avrdude version 7.1-20230306 (6c8f7e1) on ubuntu 22.04.

As mentioned reading back the written code from the chip results in something different, writing it back again the processor does not work as it is supposed. The code that works was produced by the MCU 8051 IDE programming environment. I am wondering if the hex file formats are different, ihx vs. hex, I have not really looked into this yet.

Thanks, Peter

[dioannidis]

@orbanp

Could you please test with the -B x option ( i.e. -B9 or -B11 ) ?

1      /* 500 Hz */
2      /*   1 kHz */
3      /*   2 kHz */
4      /*   4 kHz */
5      /*   8 kHz */
6      /*  16 kHz */
7      /*  32 kHz */
8      /*  93.75 kHz */
9      /* 187.5  kHz */
10    /* 375 kHz   */
11    /* 750 kHz   */
12    /* 1.5 MHz   */

There is a bug that I couldn't find time to tackle yet .... Error in read after entering PE with slow clocks

[orbanp]

The chip runs at 12MHz.Reading the chip with the -B9 or -B11 option the read files are identical, though they are different from the one read without the -B option.Writing back the "-B11" read file the code works. (Did not test with the "-B9" file.) So it looks like for the correct reading the speed option is required. Thanks, Peter

Can you test with this fw https://github.com/dioannidis/usbasp/releases/download/v1.11/Firmware_ATMega8_12MHz_TPI_HIDUART_SNWRITE_FIX_LOW_SPEED.zip ?

( Tested with an atmega8 with hfuse 0xD9 and lfuse 0xE1 )

regards

[dioannidis]

@orbanp , @mcuee

The v1.11 is released

regards,

[orbanp]

It is working!

I installed v1.11 into the usbasp.I changed in the Makefile the line from "ISP=snap_isp" to "ISP=usbasp". The read function initiates the SCK frequency to 32kHz.The read of the flash and writing it back works OK. Interestingly, the verification (read) part of the flash writing is a lot faster than the single flash read function.

I would like to thank everyone to make the AT89S52 programming with avrdude and usbasp working!

Regards, Peter

[dioannidis]

@orbanp, @mcuee

The read function initiates the SCK frequency to 32kHz.

How do you know that it starts with a 32kHz sck frequency ? You used the avrdude's -B option ? If you did please test without it .

The USBasp's probe function should start with a SCK frequency of 1.5 MHz, trying 3 times ( for both AVR and AT89S* , so it's a little bit slower ), going lower if it didn't get a valid response .

It is working!

I'm glad that it worked !

PS: ( If your USBasp device exposes the RxD/TxD signals to the connector, you can test the HID UART functionality of the firmware using the USBaspHIDUART utility. See also UART HID protocol ) .

regards,

[orbanp]

Leaving out the speed option the reading and writing still works OK!You are correct, I accidentally left in the speed option from yesterday, I have saved the avrdude commands for testing in a text file. According to the documentation usbasp does have the RXD/TXD signals at the ISP connector, however the board (a kit) with the AT89S52 chip does not have those signals connected. I guess I could put those in if I wanted... The kit originally came with a Chinese STC clone processor, that uses a different programming protocol from Atmel's using the RXD/TXD signals. I replaced the STC chip with the Atmel processor. I guess I could test the USBaspHIDUART utility with that STC chip too.Programming the STC chips there is also the stcgal tool for that (I have not used it).
