Re: [N8VEM: 14294] Re: RomWBW V2 Beta

Hi Wayne,

I did not try your binary. I build it fom sources, beceause I wanted to change the RAM to 1024, oscillator frequency and add support for PPIDE.

Best regards

Martin

Nope, problem is on my end (at least the "general" problem is).  I checked the binary I uploaded and it is broken for me too.  Looks like there must have been something wrong with the build that I uploaded.  I will reupload something this evening.

Sorry for the trouble.  I really appreciate your help with the testing.

Hi Wayne,

I also tested few different SD cards. The timeout issue was only on older slower „Pretec SD 2GB 60x“. The newer „Pretec SD 2GB 133x“ or „ADATA SD micro 2GB“ had no timout, but hte BIOS B22 freezes on all (with SDTRACE=1). Maybe the problem is somewhere else, such as speed of some ICs? I use 74ALS574 as U11, maybe I could try ordinary LS.

Best regards

Very odd.  I am testing on 5 different cards and I do not seem to be able to recreate this.  I will keep working on it.

Thanks,

Hi Wayne,

thank you. It behaves a little bit strange. If I set the SDTRACE=2, then everything works OK. SDHC card is detected as 03 and ordinary SD card as type 02 and both seem to work. If I set the SDTRACE=1 the computer freezes on first SD access. It freezes on both SDHC and old SD cards. It looks like it needs some time during initialization or so.

Best regards

Hi Martin,

I just uploaded a new beta that should fix this.

Thanks,

Hi Wayne,

thank you, it looks like you are right. I tried SDHC and detected card type is 03 too. The SDHC card works, the SD not. Terminal capture files are in attachment.

Hi Martin,

Can you turn on the full trace (SDTRACE .EQU 2) in your config and provide me with the output.  It looks like an SDHC type card was detected, but you probably have an SDSC card.  Probably an issue in the new card type detection.

Thanks,

Wayne

Hi Wayne,

I briefly checked the new B21 BIOS, but it looks like SD is not working at all. I got

A0>j:
SD: 51 00 00 42 01 FF --> RC=20 TOK=00 [CMD ERR]
BDOS ERR ON J: BAD SECTOR

I tried your compiled BIOS and compiled one myself with different settings, but the behaviour is the same.

I will check thoroughly in the evening. Maybe I did some mistake.

Best regards

Martin

Yet another refresh of the RomWBW v2.0 Beta.  It is found in the RomWBW folder<http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder&param=RomWBW> and the file is called "RomWBW2-Beta.zip".  On startup the banner should reflect v2.0 B21.

It primarily includes various compatibility fixes in the SD Card driver and support for SDHC/XC card types.

Thanks,

Wayne

Hi Folks,

I have refreshed the RomWBW v2.0 Beta on the Wiki.  It is found in the RomWBW folder<http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder&param=RomWBW> and the file is called "RomWBW2-Beta.zip".  On startup the banner should reflect v2.0 B19.

  *   Now has two different builds for N8.  One for the prototype called n8_2511 and one for the new production board called n8_2312.  The 2312 variant has the proper configuration for the new SD card circuit courtesy of David Giles
  *   Increased the initialization timeout in the SD card driver.  I'm hoping that helps with the recently reported timeout issue.
  *   The ParPortProp variant (zeta_ppp) now defaults to the VGA display and PS/2 keyboard for all console interaction.
I will leave it to Douglas to describe any/all changes to his applications.

I intend to do a final release of v2.0 next weekend.  If anyone finds any significant issues, please let me know!

Thanks!

Wayne

For any brave souls that want to try it, I have just uploaded a beta copy of RomWBW V2.  This is the new bank-switched implementation.  Although the code has been stable for some time, I would not recommend folks use this in any system that you want to be super stable.  I am making a beta version available to expand the testing and get feedback.
