I got this error when running eval.py on pet_val.record generated by create_pet_tf_record.py
#Startup failed 0xd9 code#
Since I did not write any own code I suspect this to be a Bug. I am sure that my TFRecords are valid, because I can reconstruct valid Image and Annotation data from it. I saw some guys having similar problems related to libjpeg, could it be that this error is related to libjpeg? I have build the TFRecord files with the script provided in the object detection api, but get the same for an PASCAL VOC like own dataset. When training the Oxford-IIIT Pet Dataset from Scratch (without any finetune checkpoint from COCO set), I get the following error message while running the eval.py script:Ĭorrupt JPEG data: 245 extraneous bytes before marker 0xd9

OS Platform and Distribution (e.g., Linux Ubuntu 16.04): Windows 10 圆4.Have I written custom code (as opposed to using a stock example script provided in TensorFlow): No.What is the top-level directory of the model you are using: tensorflow/models.Do you feel lucky?Īnyway, in summary: Rather than call the address of the vector table directly, you need to load the second word from it, then call whatever address that contains. The lower byte of 0x7bxx is where the base register is encoded, so by varying the address you have a crapshoot as to which register that is, and furthermore whether whatever junk value is left in there also happens to be a valid address to load from. However, the killer is that initial stack pointer, because thanks to the RAM being higher up, you get this: 0: 7b38 ldrb r0, Until you eventually bumble through all the remaining NOPs to 0x20d8 where you pick up the real entry point. I cannot understand the instruction DCW and why it goes to hard fault.Ĭan anyone tell me the reason behind this?Įxecuting the vector table is what you do on older ARM7/ARM9 parts (or bigger Cortex-A ones) where the vectors are instructions, and the first entry will be a jump to the reset handler, but on Cortex-M, the vector table is pure data - the first entry is your initial stack pointer, and the second entry is the address of the reset handler - so trying to execute it is liable to go horribly wrong.Īs it happens, in this case you can actually get away with executing most of that vector table by sheer chance, because the memory layout leads to each halfword of the flash addresses becoming fairly innocuous instructions: 2: 1000 asrs r0, r0, #32 But in the earlier case it doesn't go to hard fault. When stepping from address 0x0000 2000 ,it goes to hard fault handler. The disassembly is as follows in this case. This value is not divisible by 64 and the code is stuck.
Then stack base + stack size(0x2900) gives a value = 0x10007B38. This value is divisible by 64 and the code is running without stuck.īut ,when I select heap memory as 0x00002E88 ,it generates stack base as 0x10005238.
I found this is loaded at first locations of application bin file. Then stack base + stack size(0x2900) gives a value = 0x10007B40. When I select heap memory as 0x00002E90 ,it generates stack base as 0x10005240. After some deep debugging ,I could find out that machine was not stuck when there is a value which is divisible by 64 is at first locations of application bin file. After adding some heap memory to the code, the machine is stuck.
