Hello,

My problem is I use command prompt to program ST72324 but when I verify the checksum it shows 0xE000 which is the same checksum without programming. The command line I type : st7_pgm st72324j2 himid_st7ost.s19 0x7FA4 F. The option byte is same as what I have set which is 0x7FA4. Please advise me if I miss out something?

Thanks.

Hi JOYCE,

For now ST7_pgm can only read hex files, not s19. That is very probably the source of your problem.

Please try to convert your s19 file to hex and try to give the hex file to ST7_pgm.

Best Regards,

Vincent

Hi VincentC,

Thanks for your reply.

I have actually simply change the .*s19 to *.hex and have the same result where checksum returned is 0xE000. However, if I programe the device by using RFLASHER interface, both *.hex and *.s19 file can return the correct checksum. I am very curious why this cannot be done through command prompt. Maybe you can enlighten me with some idea?

Thanks...

Hi,

Changing the file name is not enough: hex and s19 are different formats and the contents of the files are not the same! So you really need to _convert_ the file. For that you can use a free converter, there are several on the internet. (personnally I use objcopy from gcc) But the best is to have your linker generate a hex file directly. All decent linkers can do that if you ask them.

The part of the software that reads the input file is not factorized between RFlasher and ST7_pgm. That explains why RFlasher can read s19 files and ST7_pgm cannot. (yet)

Best Regards,

Hi Vincent,

I use BINCVT to convert s19 to bin file and then from bin file to hex file but still fail to program by using command prompt. The checksum return is still 0xE000. I do not have the source code of this file so I may not use the linker to generate a hex file directly. Can you please advise any method that I can try? Thanks.

Hi,

There is probably a problem in your conversion.
(bin files are bad for devices like ST7 that don't have the start of flash at zero.)

I suggest you use RFlasher for converting. (you know that RFlasher reads your s19 correctly) For this, open RFlasher, load the s19 file, and then save the content of the memory in a hex file. (right-click in the data dump view)

Or you can send your s19 file to us (support@raisaonance.com) and we will convert it. (include a link to this post in the message)

Please also tell me which version of the Ride7 and STM8-ST7 kits you are using, and the command line you use for launching ST7_pgm.exe.

Best Regards,

Vincent

Hi Vincent,

Really thanks for your helpful info. I can now program by using command prompt with the *.hex file generated by RFlasher.

Thanks a lot.

Hi Vincent,

I have another question here. Is it possible for me to check for the checksum by using command prompt as well? Any command line to execute this checksum verification?

Thanks,
JOYCE

Hi

All the possibilities of ST7_pgm.exe can be seen from the help menu.
If you run ST7_pgm.exe without argument you will get this help.
I do not know if this is exactly expect but I think the parmeter "V" after file name can be used to do a verication ( it has to be written first after the file name).

Hi matloub,

The command line I am using now is: st7_pgm st72324j2 c:\ file.hex 0x7FA4 F

I observe that if I put V after the file name which is :st7_pgm st72324j2 c:\ file.hex V 0x7FA4 F, I cannot write the option byte correctly( the option byte is set as default = FFE7) and I also do not get the reading of checksum. By using RFLASHER, I will only need to click on the Statistics button to verify the checksum. Please advise if I did wrongly.

Thanks,
JOYCE
