MCU have other Emmc chip for map, simple insert micro SD card and switch map from Emmc to external microSD card. For this use toolbox or Linux she'll commandHi. It seems i hit this problem too with my S75D with MCU1 HW2.0.
About 14 month ago the eMMC recall was done and the Tegra board was replaced. It seems to be a repaired one with the 64GB chip. Done by tesla SC.
After it got 2021.24.28 it began to download the maps update EU-2021.8-12875. The download stopped at about 20% and did not move withhin many days. MCU reset did not solve too. First problems with showing map tiles began in the time the map was downloading. After about two weeks the map download was still at same place and the speed was 0 B/s got blach screen for the first time. It took some tries and about half an hour the screen to come back.
Few days later the same happened a second time.
After this a friend recommended to do a redeploay from service mode. This was sucessfull, after the redeploy the map began to download again. We let it download, it tool almost 24 hours to download and install the map (wifi and internet speed was not limited and >100Mbit availible). The MCU worked fine and i did few drives that day without any issues.
Next day started with a black screen on MCU, after reset by roll buttons it came up and hanged after a minute or two.
Removed the MCU and send into service to check all possible things.
Both eMMC chips, filesystems and NOR chip are in good condition. Done backups. One filesystem corruption was repaired. The MCU still remains black screen.
Will reinstall the MCU tomorrow and bring the car to Tesla SC for repair.
There is no microSD card in the slot.
Any ideas?
