ok, tried without tweaking those eeprom sizes. flash went fine, but boot failed with below uart log:

Please still set CVB size with 0. CVM should no need to be changed.
Just to confirm, we still need to set
eeprom.cvb_eeprom_read_size = 0 for both tegra194-mb1-bct-misc-flash.cfg and tegra194-mb1-bct-misc-l4t.cfg.
Yes, please try.
Was this board able to work if you set both eeprom read size to 0 in last time?
No, never worked, see my last comments in the last thread.
Which thread? I am asking about the original jp5.0DP without any overlay.
Was your board able to flash + boot up if you set both eeprom read size to 0 in that BSP?
If the board was not even boot up in that case, then it is different issue. Actually, your log looks like a different issue because MB2 already done. If this is same issue as previous one, then it shall got stuck in MB2 but not UEFI.
this is the post I had in the old thread that is already closed. I mentioned in that post the board didn’t come up even after modifying the files.
I just tried again after applying the overlay, and set
eeprom.cvb_eeprom_read_size = 0 for both tegra194-mb1-bct-misc-flash.cfg and tegra194-mb1-bct-misc-l4t.cfg and got the same error above.
Could you also set
eeprom.cvm_eeprom_read_size = 0 for your case and see if you can boot?
The log you just posted is different from what you hit last month. I feel these two are different issues.
Tried that, same error.
BTW, is that a way to flash everything except the APP partition? It takes a long time to push the system image to APP partition through the USB. Since we didn’t change anything in rootfs, it is a waste of time.
Is this still an issue to support? Any result can be shared? Thanks
I am working offline with neelp and cfritsch from nvidia team. We can close this.
